I had read a few bad reviews of these items before purchasing them. Like those reviewers before me, I found it was hard to ignore the low price. So I asked myself, "How bad can they be"?
The brush heads I received looked correct when compared to the brush heads I purchased locally (at much greater expense). When using them, however, I notice that the motion of the head is not nearly as controlled as the retail example. On the local retail version, the motion of the head is very well constrained to just an oscillating motion (partial rotations, back and forth). These brush heads have very poor motion constraint. The circular brush can easily "slide" around on its base which can very easily pinch your cheeks and/or lips (sometimes quite painfully).
Not only that, but the oscillating motion is much weaker resulting in a worse quality brushing. As poor as the action of these brush heads is, I can only imagine that they are a cheap "knock-off", more interested in looking like the original than acting like it.
My advice is to pay the retail price for the real brush heads. Your mouth and your dentist will thank you.

I ordered "Oral-B Precision Clean" and that was also listed on the package invoice.

I received the Euro-packaged Flexisoft, which are useless! I've used Flexisoft for years and I know a good/new from a bad brush; these were soft/er out of the package than should be after 3+ months' use.

Kabat Enterprises, LLC / US Health Tests promptly refunded my money when I complained, and that is why I have removed my negative feedback for the seller.

Posting this feedback to warn others of the product swap and performance.

BUYER BEWARE!

don't buy these, they are cheaper, sure, but I bought them and each one of them broke (the moving brush part came loose) after about 2 weeks, far before the bristles were showing any sign of wear, so actually they turned out to be way more expensive then had I paid more and bought the Oral-B brand!!

I love this product,perfect for kids. transaction was fast and most of all good deal. I will buy again.

i bought this for my electric tooth brush replacement, and oral b is alway has good reputation of making tooth brush, but please stay away with this one that sold here (Oral-B Precision Clean Replacement Brush Head (4 ct.)
). the quality is suck.
