I had the old model which won't recharge any more after two years of use. I still have extra brush heads left unused. I ordered this model because it looks like from the pictures that they use the same brush heads. No, they don't. The old brush heads won't fit into the new model. At least this package comes with extra brush heads. I definitely won't order extra brush heads this time until I need to. The wireless charging uses an USB2 plug and there is no power adapter included.

I bought one a year ago, but this one is the another beach. I bought as a spare, hopefully as good as the first one I bought. I have not open yet the charing system is at the base not like the first one without base.

Happy with these, I think they might even be better than the originals that came with my brush. They have caps to protect for travel too.

I like this one better than the Philips / Oral-B brands.

Perfect size, perfect price!

After I ordered this replacement brush, the main handle stops working. Now I have no use of this at all.
