Imagine your car with punctured wheel you replace with a spare wheel. This is exactly the image I have of its compatible brushes.
Why avoid it?
- This is 2 times noisier than a true oral brush B. I hesitate even to use it after midnight. I feel like too much noise.
- Product quality is very average, despite a great similarity
- The hairs hold the teeth more or less
- The shelf life is shorter than a real brush
- It brush less
So yes it helps out, but the means that we use every day, I am fairly convinced. It's still a spare tire!
