I love this toothbrush!! Been using it for a couple months now and I love it! My teeth are noticeably whiter and cleaner. The Bluetooth function is interesting and kids would probably really enjoy it, but that function hasn't been necessary for my use.
My family has been purchasing these sponges for years! Love how it has the two sides, the soft side is good for plates and stuff but the rougher side is great for pots and heavily soiled cutlery. They do tend to harbour bacteria though, so they should be rinsed thoroughly after each use and left to dry.
