Sometimes my gums bleed. On average, it bleeds once every 3-4 days. But since I started brushing with these brushes, this rate has decreased a lot. I think it bleeds once every 9-10 days. This is a good thing I guess.
Since it has universal heads, it is compatible with every brush at the rate of 80%. I've tested it for several of my friends', mom's, and wife's toothbrush machines. So, I tested it on a total of 5 friends' toothbrushes.
Not compatible with my wife's toothbrush machine.
It was compatible with my friends' toothbrush machines.
It was compatible with my mom's toothbrush machine.
So, thanks to these brushes, I can brush my teeth perfectly. If my toothbrush breaks down while traveling or on vacation, I will be able to brush my teeth thanks to these heads.
16 toothbrushes is quite a lot. Some people change their toothbrush every 6-12 months. I change it every few months. I used one of the brushes to clean my keyboard. (Haha!) :)
These brushes feel very cheap and comfortable. My gums are not bleeding. They are very good at cleaning teeth.
