Review on HAMMER Spinbrush Ultra Toothbrush Medium by Sarah Greenwood

I love these things. I've been using them for several years now. The only problem I have is that they don't like changing batteries. Many times I tried to change the batteries so it stopped working intermittently. Doesn't like batteries. Batteries are usually slightly larger than standard AA batteries, so they don't quite fit in. But even if you use regular batteries, the O-ring on the battery compartment will wear out over time, forcing you to buy a new toothbrush. So of course I can use maybe 3 extra brush heads, maybe 5 max before the brush becomes unusable and needs to be replaced. They're pretty cheap, so that doesn't bother me too much. As they work, the round part of the brush rotates about a quarter turn to the left, then back to the right and left again at 3 o'clock, and soon. As the floor moves up and down. There are soft, medium and hard tips. I usually choose medium or soft. The dentist told me to stop using hard tips. Soft ones don't last as long, but are gentle on gums and enamel. Since I've been using them, every time I go to the dentist, the hygienist tells me that my teeth are very clean and she hardly has to do anything to brush her teeth. Of course I brush my teeth long enough and very carefully. So if you're in a hurry to get it over with, your results may vary. I love it. For the price I can't complain. The results speak for themselves.
