Overall I’m very pleased with my Spotlight Pro. There are a couple of little niggles, though. The on button does not stand out from the body and when in use is hard to activate or to see what setting you are using without removing it from your mouth and spraying toothpaste everywhere. The pulse of the brush even in low setting is quite strong and irritates my tongue, but I’ll probably get more used to it. The unit is a nice slim profile and much easier to keep clean than my previous Oral B brush. I drink red wine and tea and, with a slightly overlapping lower front tooth, it tends to get stained. The efficiency of my brush, with 4 power settings, is leaving me hopeful that it will resolve that problem. I enjoy using the brush. It would be good if replacement brush heads were available in supermarkets etc. I suspect they are only available on line.
