I've been using an electric toothbrush for years and this oral-b toothbrush works the best and is on the lower end cost wise. My only complaint with this toothbrush is that it can mold after awhile because the toothbrush head is hard to get completely dry. I usually replace the toothbrush head every 3 months if not sooner if I see mold and the last time I had to replace the actual toothbrush it had lasted about 3 years(on my second oral-b vitality toothbrush now). Performance/Cleaning It does a great job cleaning my teeth! On my last dentist visit I was told that I had no plaque and that my dental hygiene was perfect. I completely credit that to this toothbrush. Durability It lasts as long as it doesn't mold (which seems to be a common with electric toothbrushes). It is a rechargeable toothbrush(yay for not wasting batteries). If I can recall correctly the first charge needs to be a full twenty-four hours and after that it differs in time depending on much it's used. I usually charge mine once a week at night, just plug it in and forget about until the morning.
