Title: Brush head become loose after short period of time
Review: I purchased this Oral-B Precision Clean 4 pack replacement head, I highly doubt if this is original Oral-B product. After few weeks of light use, the brush head became loose and wobbling causing extra noise, it pinched my lips and tongue. I am on the 3rd brush head now (out of the 4 pack I bought), they all broke the same way.I remembered I bought the 2 or 3 pack replacement brush head from Target before, they worked exactly like the original, but expensive. That's why it was so tempting to get this cheap "thought to be original" alternative. Be aware!
