Review: Amazing product, not the best process with shipping however could've just been me.
Review: This is the third one I have owned. I read the reviews and it seems hit or miss. After 10 plus years of using the black diamond here is what I can tell you. If you press too hard (apply to much pressure) while brushing it causes slop in the sonic arm that the brush head engages. This arm has a gap set inside the handle and is held in place by a small screw. You do not need to push at all on the brush. If you do and the arm is wobbly and you don't feel the sonic motion, it can be fixed pretty quick. There are vids on YT that show you how to reset the gap and tighten the screw step by step, note use some locktite when reapplying the screw. There are also vids that show you how to replace the battery and actual upgrade it!! On the first 2 I bought, I applied too much pressure and was frustrated with the toothbrush. So I took it apart before trashing them and stumbled onto how to repair the $300 toothbrush. Phillips was of no help either. So you may ask why did I continue to purchase and repair the black diamond? Fair enough! Its because for 10 plus years I have had consecutively perfect dental appointments! Everyone of them! Very minimal cleaning, in and out in about 30-40 mins each visit and told keep doing what you’re doing. So its pricy, you need to know how to use it properly, Phillips customer service is ehhh, can be repaired and most importantly it WORKS! All three are still charging and working flawlessly! I have one for home, one for travel and a back up. Had I known you could repair them I would not have bought the second one. This one was on sale and ridiculously priced so I bought it.
