I'm really into high tech gadgets so I researched quite a bit beforehand. I am pleased about my choice so far. This brush is great cause you can customize the pulsations to how sensitive your teeth are. Mine are medium to sensitive, so I've put it on a low intensity for now and will build up slowly. I am really keen on the timer too. It pulses every 15 seconds, to tell you to move on to a different part of your mouth. It also has a time duration of 2 minutes and then turns off, but I generally go on for a bit longer just cause it's such a nice feeling on the gums! The bristles are also long and wide so I feel like they are doing a good job covering all the surface area with each clean. I definitely recommend!
