Review (1/5): not good. extremely flimsy tab "soldered" to the battery
not good. extremely flimsy tab "soldered" to the battery. I straightened one tab to solder it to the toothbrush, and the tab just came off! I tried to solder it back, but it just slid off over and over! And I am not sure what that circle thing is that was included. Its not a mouse pad, so it just became more crap for the landfill!
