Before I purchased this, I did my homework thoroughly. I asked Dentists what to buy, asked friends what they used and ,of course, read reviews on Amazon.
I now have this fabulous toothbrush and it's proving to be the best thing I have ever bought.
It leaves you teeth feeling like they do when you have had them professionally cleaned. It takes a bit of getting used to as you don't "Scrub" but just gently guide the brush around the 4 areas of your mouth. The Toothbrush helpfully beeps at you every 30 seconds to remind you to move to the next quadrant. This 2 minute cycle is far better than my previous haphazard regime with conventional toothbrushes as it enforces a comprehensive brushing pattern.
I have been using it for 2 weeks now and have no coffee stains and my teeth are visibly whiter. The feeling of clean teeth lasts almost all day after a morning brush.
If there is more than 1 of you in the family, you will need to purchase additional brush heads (not currently sold by Amazon). I found a single costs £15 and you can buy a double pack that retails for £25 but it's genuinely worth it.
