would recommend oral-B precision
excellent value. seemed alot of money at first, but well worth it every penny. it tells you when you press too hard, very easy to use easy to change heads. takes 17hrs to charge 1st time, but lasted almost 10 days using twice a day. you cant replace your teeth or gums once they have erroded. with this brush you cant push too hard it will flash and stop if you persist. excellent!
