I'm always sceptical with Facebook ads so thoroughly researched and checked the company out before purchasing. Ordered the ultrasonic tooth cleaner and it arrived in a few days. All very well packaged in a nice box with all the parts needed, charger cable, spare heads and mirror. I must admit when I opened it it was worried about using it due to how sharp it looked but once I started to use it it only works on teeth as stated and not on gums or tongue etc. Started off on the soft setting to get use to the feel and vibrations and it's amazing, has cleaned all the stains off the back of my teeth. I highly recommend buying one of these to use as a regular part of your dental car in-between your regular dental check ups.
