I've been using my new Sonic 2.0 brush for a few weeks now which I bought to test out instead of the usual rotating head electric toothbrushes I've been using for years. I'll definitely be sticking with this one! I've been guilty of over-brushing previously (according to my dentist) and caused a bit of damage to my gums, but the sonic brush heads are much gentler and it doesn't feel like thats an issue any more. Saying that, it still packs a punch! My new routine is to run a full cycle on whitening mode, followed by at least a minute on polish mode, and my teeth feel great afterwards. It's also nice and compact just like the Sonic Travel toothbrush I bought from Advanced a while ago, and lasts ages on a single charge. Super happy with it. I'm definitely converted to the sonic brush as my full timer!
