This is the second one of these that I have had, the first on lasted about 8-10 years. the battery finally gave out and I bought this 4100. I is the same as the old one except the charging base is a little better.

I think it is an excellent buy.

I have been using sonicare brushes since 1987. I have also purchased them for several of my children. This was a replacement. I have found that my teeth have had fewer cavities and my gums have been healthy while using this toothbrush. I would not use anything else.

Great toothbrush. Love it for traveling also since it keeps it's charge for a period of time.

My old one quit after 8 long years. I did try to find a replacement
since I had some brushes for this model. The brushes are costly, but
I had some from a cvs store which did open. The vendor was great,
and I was real happy with my old brush. Why I did go for this one-
cost, and value! I do think this model is now outdated, it suits well!

I enjoy brushing with the Sonicare 4100 knowing that I'm helping to prevent gum disease. I only wish that this model had the 30 second intervals like the original model I purchased over 10 years ago.

This Sonicare toothbrush is only supposed to last 2 years. Our other one just gave up the ghost after 8 years of use by my wife and myself. We were so happy to find the same exact on on Amazon.com. Thank you so much for your wide variety of products that can be ordered from your site.

Battery lasted less than a year, brush replacements are bulkier & more complicated than need be and are too expensive

My wife and I have used this product daily for more than 10 years...and the unit was placed back into the charger after each and every use!!! A truly amazing, quality product based on our experience.

I've used the Sonicare Advance toothbrush for almost ten years and I'm very happy with it! I always got tons of cavities with normal toothbrushes, but I have only had two cavities in the ten years I've been using Sonicare. I'm also happy to say that I haven't had to have any scaling done since using the toothbrush, either. The toothbrush also made my teeth much whiter when combined with PeroxiCare toothpaste. My first brush lasted almost 7 years, and my second one is still going strong at 3 years.

The only thing that I don't follow on the instructions is charging the toothbrush after every use. My understanding of batteries is that when you charge it before it is completely drained, you damage the battery cells and then it won't hold a charge. I only charge my toothbrush when it blinks to indicate the battery is low, usually once every few weeks. The battery in my first one lasted 7 years because of charging it in that manner and by not charging it after every brushing. Since the batteries in these toothbrushes are NOT replaceable, I made sure to get the most life out of it.

Overall, it's a great product and has become less expensive over the years. A brush head lasts 6 months, so even though the replacement heads cost more than standard toothbrushes, you only need to buy 2 a year.

NOT MUCH TO SAY ABOUT THIS PROCDUCT EXCEPT IF YOU NEED ONE, GET IT.
IT HAS HELPED ME TREMENDOUSLY WITH GUM PROBLEMS.
THIS IS MY SECOND ADVANCE 4100. THE LAST ONE LASTED APPROXIMATELY 14 YEARS BEFORE IT DIED.

Here are two things Phillips will not tell you about their Sonicare toothbrushes and heads.

1) The collar that holds the toothbrush to the handle will disintegrate in a couple of months. That's what prompted this review, because they would not replace mine after it fell apart two weeks after purchasing a replacement.

They manufacturer these things to disintegrate so you will continue to buy replacements - planned obsolescence. However, I suspect their China supplier is skimping on the plastic specifications and they fall apart in weeks instead of months. (Do you think China would really do that?)

2) UNPLUG your base until you need to charge the toothbrush. If you charge it up overnight, then unplug the base, the toothbrush will work for four brushings per day for about a month. Then, when it signals or stops, plug the base in to charge it.

This method will allow your toothbrush to work for five years or longer. If you keep the base plugged in all the time, these NiCad batteries develop memory and will stop functioning after 18 to 24 months.

A bonus, if you travel a lot as I do, you don't have to pack the charger. Just make sure it's topped off and you're good for a month's vacation.

We bought the kids one of these for each after the cheaper Sonicare Xtreme E3000 Power Toothbrush - Orange failed repeatedly - we actually had Amazon send us replacements.

These are the perfect way to introduce tweens to a toothbrush that's going to keep their teeth happy, clean and healthy for as long as they need to bite and chew things. They've been using them for almost one year now and they work as expected. No breakdowns whatsoever and the price is absolutely right.

If you don't want to spend more money on an Elite, then definitely go for one of these because it's the next best thing.

My teeth have never felt cleaner. I could tell a difference in just a few days. I know it's the basic model, but that's really all you need. No need for all the bells and whistles.

My husband and I used SoniCare for our toothbrush - bought our first one in 1994. Well - this year the toothbrush finally died - no longer held a charge. Ours was the only SoniCare model sold at the time we bought it - it worked VERY well for a very long time. We changed brush heads every six months, we kept the unit well cleaned. We really loved the heft of the base unit and the 30 second beeps.
So we ordered another "basic" (to get the HEAVIER base - we did not like the lighter weight model with those SKINNY brush heads). This SoniCare arrived a week after we ordered it - well packaged - all items in tact. We 'pluged' in the charger - charged the brush unit 24 hours - and then - proceeded to use it.
COMPLETELY CHANGED - - - now, NO 30 SECOND BEEP - the unit does work for the entire two minutes, but gone is the very handy 30 second timer.

I do believe we will change to the Braun Oral-B when this piece of dreck dies. It's not pleasant spending a weeks grocery money on a toothbrush - and then discovering that the 'trusted' company decided to make a few pennies more per item and killed the 30 second timer on 'low-end' items.

Shame on you Phillips/SoniCare!!!!!!! (Sure hope those few pennies saved make up for the LONG time customers you are going to lose.)

I am very pleased I found this item on Amazon. The price was descent.

I have owned electric toothbrushes before. I had a braun for several years and then switched to manual. I don't remember this dentist clean feel after brushing with my old tootbrushes. I bought this here for $55.00 with free shipping. Only to see it at Bed, bath and beyond (BBB) for $39.99, 3 weeks later. With the 20% coupon that you get in the mail every month from BBB that adds up to your savings. So check BBB first before buying it here.

Great product. I had been using an ordinary manual toothbrush, and my checkups were good, but not great. My dentist said the Sonicare is the best for the teeth and gums, and I agree. Mine have never felt cleaner. I'm anxiously awaiting my next appointment to see if my pockets have gotten smaller.

I purchased the closest Sonicare model to the one I had which died after 5 years of use. Unfortunately, this model does not have the 30 second pacer, which I really loved with my original one. It may have been a good time for me to upgrade to the newer model, but I had just purchased two packages of the replacement heads that went with my original model. As the replacement heads are not inexpensive, I bought the same model in order to use them. Next time, I'll read the product features more carefully before ordering!

I would like this much better if the batteries could be replaced. I had to throw away my sonicare even though it was perfectly good because the batteries had worn out. I was trying to replace the batteries since they're standard AA Ni-CD, but in the process broke something on the PCB.

I could have had more years of usage on this thing otherwise. Having to throw away a perfectly good item seems so wasteful.

I already owned a Sonicare 4100 and it has been a very reliable and effective tool. When traveling to my second home, I brought the toothbrush but forgot the charger so I decided to get a second one. The Amazon price was very good and shipping was free so I ordered. The new 4100 is exactly as good as my earlier 4100 except that I was unaware that it comes either with or without the feature to let you know when each 30 seconds of the 2 minute cycle is up. My old one has this feature, the new one does not. That was a minor disappointment as I thought I was buying exactly the same product.

I purchased this toothbrush a few months ago and am extremely pleased with my purchase. It took a week or two for me to get used to brushing with this new brush, but once I did its been great. My teeth feel like I just got back from the dentist when I finish brushing. Also, one charge lasts 2 week easily for this brush. I would highly recommend this brush for anyone in the market for new one.

System is a very fine system. I had the same product for about 6 years prior to this one.

The Philips sonicare advance series is a piece of junk. On my first purchase
I noticed that the replacement heads never lasted the six months they are
supposed to last, cracked in less than 3 months.

When the handle cracked (after about 18 months) I bought another.The new one,
the handle cracked within 3 months, and lasted less than a year.
the heads cracked and did not last even remotely close to the
6 months they are supposed to. I've tried this brush twice,I'm through
wasting my money, I'm going to Oral B (Braun)

Best sonic toothbrush on the market. Far superior to the newer Sonicare series, which have brushes too small for a normal sized male mouth.

I don't know why, oh yes I do, money, manufacturers make "new and improved" versions of a good product. This is one of them. Each time they come out with a "newer and better" version it doesn't work with the previous one. This one is one of the first, it works great, have had it for years, buy the heads regularly; then when I go to the store to get new heads, they don't carry them any more because the older model is out of stock and the heads on the newer models they do sell don't fit the older model. In other words, the manufacturer is forcing one to buy the new model, heads and all at a higher price. But it is nice to know that Amazon carries the heads and the bodies of the older versions, that is until ... well, who knows.

I initially received this toothbrush as a birthday gift from my husband and I wasn't very pleased. But now I am thrilled. My teeth are cleaner, my dentist is happier, and once you use this toothbrush you will never want to go back to a manual again.

The Sonicare works as advertised, noticed a difference right away - it's like going to the dentist to get your teeth cleaned. Couple of things to keep in mind, it is (like any power toothbrushes) a little messier than a manual toothbrush especially when reaching the back teeth. The brush should be removed and rinsed after each use as liquid runs down into the base area of the brush.

Only problem, one of the tiny magnets on the end of the brush came loose somehow and stuck to our sink fixture. We didn't notice it missing right away and the next time the brush was used, it didn't seem to be vibrating much. We thought the unit was defective until I noticed the missing magnet. Stuck it back on and it worked perfectly; although, it must be in the correct orientation. Seems like they are simply magnetically held in place, maybe they should be superglued as well.

I'm so satisfied with this purchase. It cost half than what the other brands charge (I had gotten it on sale here for $40) and it leaves your teeth squeaky clean. I noticed my teeth had gotten brighter after 2 weeks (and I thought that was just a marketing gimick). I don't think I'd ever go back to manual brushing now. I actually look forward to my 2 min. per day brushing every night.

Soon you'll find that two minutes with it is not enough. But it does take a little practice and learning the best technique at first. Highly recommended.

And one of the best Gold Box deals of the day. This is the 2nd SONICARE we order from Amazon's Gold Box for my husband, after I got one for me a couple of months ago.
An awesome toothbrush!!!

This toothbrush is everything I expected and more. The toothbrush leaves a sensation in my mouth that is tough to describe. It is like I have had my teeth cleaned by the dentist...

This item is great. I give it 5 stars. You have to get use to the vibration like others reviewers have stated. Several times after using the toothbrush, I have tried to floss and its a waste of time because there is nothing to floss. The toothbrush takes care of it all. I feel like I just left the dentist office after a cleaning. I have sensitive teeth and the sensitivity is starting to diminish. Great product.

Ever since getting a Sonicare about 10 years ago, I have had excellent dental exams. These brushes make brushing fun. The special price by Amazon allowed me to get everyone in my family one.

it is my first time to use sonicare. it is totally different than other brands i have used. it feels very good and give you a fresh feeling of mouth every day.

I got this a birthday present for my and she loves it. She said her teeth eel smooth all the time.
