Bests & Worsts Reviews from Amazon

Potential false advertising. Product Details state the following: "Batteries 2 Lithium ion batteries required. (included)" The user manual states the following, "The power source for this product is nickel-metal hydride battery which can be recycled." I took one of the AquaSonic toothbrushes apart to confirm. Yeap - NiMH batteries. See photo. Some of these products are trying to distinguish themselves based on battery technology. Do your research first. Looks like Amazon updated their product description. They removed the statement :"Batteries 2 Lithium ion batteries required. (included)". I mentioned this originally because lithium battery technology is just better than NiHM.
