Review on Philips Sonicare EasyClean HX6511 sonic toothbrush, white by Minoru Koshida ᠌

This is my second Philips Sonicare brush. The first one was the same, but then I did not understand what the problem was and threw it away. The brush in the second year began to give out a smaller amplitude of vibrations, I began to feel that the cleaning was not of such high quality. I disassembled and understood what the miscalculation was - the vibration module is attached to the motor with two ordinary bolts ! Naturally, this whole thing vibrates, we drop the brush (here we must pay tribute, the protection from blows in the brush is at a height, do not be afraid to drop it) . as a result, the bolts weaken and the vibration module shifts, the clearance between the vibration module and the motor changes and the vibration from this suffers. I made a short video on this topic, look on YouTube for the video "Philips electric toothbrush loses power".
