Review on Philips Sonicare W3 Premium White Replacement Toothbrush Heads - 4 Pack, HX9064/65 by Danielle Miles

I have a friend who works at Philips and heard that the developers are very proud of these new heads. Their new technology prevents the brush from vibrating/brushing even with light pressure. Even if you try to get at the molars, and the only way to do that is to squeeze around them, it will stop vibrating. This rendered this toothbrush useless. For real. I've been using Sonicare for 20 years and have never had any problems with receding gums, in fact data from the dentist shows it has helped stop it. I've always bought branded lots due to my budget, but this time I decided to try the official ones. Thought maybe there's a reason it was worth it. But now with these new heads my teeth won't brush and I have tartar again. My dentist was very surprised at the six month difference. The only change was these toothbrush heads, I stopped buying generics. But back to generics. The price difference I paid for the Sonicare was EXTREMELY disappointing.
