I am very happy with the Oral B Vitality electric toothbrush. It is priced reasonably and does a great job.

I know a lot of people complain about its big size and what not...but personally I didn't face that problem at all - - if anything, the big size is its biggest merit personally...I have this, the FlossAction and the Regular refill...yet I personally like this one the most

The reason for that is that its pretty much the closest to a traditional toothbrush considering its size...and since I'm "extremely" used to the regular toothbrushes, this serves as a good way to make the transition to the electric toothbrushes (besides I like the regular size toothbrushes anyways so this is automatically a better option for me than the others)

Another thing which is very important for me is that since it has a bigger size, it allows more paste to be put onto it...this therefore, allows more paste to be used while brushing...frankly, the other size refills do a fairly good job as well, but I personally feel that I'm not using enough paste while brushing with them - this solves that problem since it uses almost double the amount

Then ofcourse we have the DualAction which one might consider the most important aspect of this refill...personally I couldn't tell if it was actually making a difference as such - I simply use it as a normal toothbrush and the DualAction simply functions as a bonus - instead of something I genuinely care about...I do generate quite a bit of toothpaste goo...but I suppose that's normal considering the continuous rotations of the toothbrush + the extra paste used in this refill compared to the other ones

To summarize the keypoints:

Pro's
1) Large size makes for a traditional feel if you are making a transition from the regular toothbrushes to the electric ones
2) Large size = more paste being used
3) Dualaction (could be considered an advantage for those who find it useful)

Con's
1) More paste = more goo
2) The large size may not suit everyone as some might feel that the size is a little too big (I personally don't...but I can imagine others feeling differently - it really depends on what size of toothbrushes you generally prefer I'd say - I need a large size for example)
3) Dualaction (i couldn't really differentiate between the two functions while in use so I'm considering it a con - but it wasn't something I genuinely cared about so it doesn't affect my final rating)

Other than that you really can't go wrong regardless of which refill type you select - just as long you select an electric toothbrush in the first place (I could certainly tell a big difference between regular and electric toothbrushes)

Hope this helps! I'll be sure to add more information if I find anything else worth considering

Be sure to order replacement heads from Amazon with FREE shipping. Keep several brush heads in stock to replace every 3 months or when color begins to fade from brush. Fewer cavities, reduced tartar and plaque, healthier gums, fresher breath! Great system.

I absolutely love my Oral B toothbrush but I really wanted this bigger toothbrush head instead of the one that comes with it. With an "old fashioned" toothbrush, I always looked for the most bristles I could find so I was surprised to discover I actually prefer the smaller Oral B toothbrush head to this one!! The simple reason is that with the smaller head (with just the cicle of bristles), I feel like I have more control and can really get around my back teeth. This will really boil down to preference for anyone. I'm sure both are great at getting your teeth clean. But for me, I am going to stick with the standard head that comes with the toothbrush.

These refills were relatively simple to find but I was a bit apprehensive that they might not fit my toothbrush however, they turned out to be a perfect match. It took a little more time to be delivered than was the norm but they did finally arrive a few weeks later.
Thank you.
