Review (2/5): No Li-ion battery and not waterproof!
Wow. It's 2018 and this thing comes with NiMH batteries instead of Li-ion?? How did I miss that-? It's my bad of course. Claims 10 days of charge. It is also not very happy getting wet it seems. "Do not use while bathing." That's one of my favorite things to do with my Sonicare. I LOVE the looks of this thing and was willing to pay the price but no Li-ion and not being able to use it in the shower ... wow. And replacement heads are $20 for 2. I am so eager for someone to make a USB chargeable electric toothbrush that is well thought-out.
