Review (5/5): First time user
I bought one for myself and one for my 14 year old son. We both love it and the timer is a great thing for both of us, especially him! The toothbrush pulses at the 2-minute time. This toothbrush really makes your teeth feel clean and works great compared to a regular toothbrush. I charge it about every 4-5 days, just to keep it going really fast. My son leaves his on the charger. Both ways are fine so far. we have been using them for three weeks or so.
