Review on Electric Toothbrush Replacements Compatible Bristles，4 by Louis Nakashima

At first I was happy to find a cheap replacement for the more expensive Oral-B tips. Unfortunately, I was disappointed with how long these heads would last. I only had about 3 weeks of use before they stopped working properly. If you look closely at the head, it stops spinning back and forth after just 20 uses. This happened to all 4 of these nozzles. If you're already using them, after a few weeks take a good look at the heads and there's a chance they're not blending properly and not cleaning your teeth properly (they just vibrate with no movement, so they seem to be working). , they actually don't). I've now reverted to the original Oral-B tips and they last 3+ months easily.
