Proden Plaqueoff - teeth cleaning product - has anyone bought for their dog?

Thinking of buying this, which has some good reviews on Amazon: http://www.amazon.co.uk/gp/product/B000QAEQXQ/ref=noref?ie=UTF8&psc=1&s=pet-supplies

It's on offer on Amazon's Lightning Deals at 10:43am today, so price should drop usefully for a couple of hours then.

Anyone bought it or aware of any dogs that have used it?

Thanks.

i had this product from the vets for sasha,seems to be working but i do brush her teeth now as well,i have seen it for sale at pah,i think it was around 18 pound,in our branch its not on the shelve you have to get it at the tills   

We just use the doggy toothpaste from Pets at Home on one of those finger toothbrush thingies and give it a good smear around.

My mum and sister both use this and say it has made a difference
