Pack of 10 Replacement Heads Compatible with Oral B iO 10 9 8 7 6 5 4 3

These are terrible. Earlier review are better, so don't be fooled like I was. In using up the last of my OEM heads, I am now outside my return window. The plastic is harder or more brittle than the original; the quality just FEELS poor. There are a multitude of additional problems. This head fits TOO tightly onto the handle. You really have to *jam* the head on to the handle. Additionally, when in use, the noise is much MUCH louder than when using an OEM head. It is obnoxious. The amount of water leakage/sudden geysering of toothpaste and water when using makes each attempt to brush my teeth an exercise in flood management and results in the need for additional cleaning of countertops, mirrors, etc. In short, these are NOT worth the savings over the OEM heads. I'm likely going to have to throw them out and waste the $25 I spent. Read more

These do not operate similarly to the original heads. They dont rotate the same and the brushes are so stiff they hurt my gums. Read more
