2 Pack Sonic Electric Toothbrushes
Each toothbrush arrived with a USB cable and was easy to charge.  Coming up on 30 days and they are both still charged and working great.  I love the double brushes and the extra 8 (amazing) brush heads.  I had an expensive name-brand electric toothbrush previously, but I don't feel it cleaned as well as these.  The only dislike I have is that you must run through all of the modes to turn off the brush.  The 2nd toothbrush is for my dog.  The sound and vibration are quiet enough that she enjoys getting her teeth brushed with her favorite doggie toothpaste.  These are waterproof, so easy to keep clean.  I'm very happy with my purchase.
