Q & As

Philips Sonicare HX6511/50 EasyClean Electric Toothbrush 4.4 5 20 20
Great clean but poor reliability These do a great job of cleaning teeth - much better than the Braun Oral B in my experience (dentist no longer needs to descale my teeth). However we are now on our 3rd toothbrush in 14 months, the first 2 having developed exactly the same fault. The tooth brush begins to rattle and the energy to the brush head is lost so it no longer cleans. Reading reviews on Amazon this (and battery failure) is very common with many brushes expiring just after the warranty expires. Can't fault JL 2 year warranty that has just refunded the cost of the second brush - and I will buy another because they work so well - however they seem to have built in failure. 30 December 2014
Usual Philips unreliability - good while it lasted! I bought this 7 months ago. I was a bit dubious about buying Philips having bought their products in the past and them being not terribly reliable. Well things haven't changed! Mine is going back soon, the battery has stopped holding it's charge. My wife bought a Braun months earlier than me, hers is still going strong. Also the heads are very expensive compared to the alternatives. I will be replacing mine with a Braun. 23 November 2014
Very good product at good price Like other reviewers, I had a more complicated and expensive model of this toothbrush, but didn't use any of the extra features. It died after 2 years. This model does what I need it to do. The only disadvantage is that there are no stands on the base for the brushes when you are not using them - not a big issue. Brushes for all the Philips toothbrushes seem to be getting softer and not lasting as long, which is annoying because they are expensive. 04 November 2014
Buy it This is my second Easy clean toothbrush sadly they don't last forever! Cleans really well couldn't go back to a manual toothbrush after using this. 30 September 2014
perfect clean Best Electric Toothbrush l've ever had. Perfect for all the family. Really good clean. 09 September 2014
Works well and stays charged for ages My previous Sonicare (with extra fancy features which I never used) conked out after a couple of years, as they tend to. This replacement was a good price and has no unnecessary bells and whistles, it does the job well and so far has been a month without needing a charge (we tend to use it in the evenings and brush manually in the morning). The previous one used to need charging after a week or two. An excellent product. 05 August 2014
Good Value Good Value, easy to use toothbrush, gives good results! 16 April 2014
Good product, great price Was told to buy this by a friend as the best toothbrush around. Don't need all the features of more expensive models. Very happy with this which is working well so far. 09 April 2014
