Title: Knock-off product, poor quality
Review: These Oral-B Vitality/Precision Clean heads are not the same quality as the original head that came with my Oral-B Vitality toothbrush. The original head lasted for several months, but these do not last as long.I've used 2 of the 4 so far. The first was considerably noisier than the original head, but not wanting to waste it, I continued to use it anyway. After about a week of regular use, the part of the head that rotates became looser and looser. It was falling apart. I threw that one away, and moved onto a second. This one is also very noisy. I'm afraid that this one is falling apart, too.I will buy more replacement heads from a different seller. I do not recommend this seller's product.
