Review on Dazzle Your Smile with Sonicare HX6066 70 DiamondClean Standard: Unveiling Superior Oral Care by William Lara

5 out of 6 toothbrush heads are great. However, one of them makes a crazy loud noise when used. So loud that I could hear it from the living room while my wife brushed her teeth in the bathroom. Our house is about 2800 square meters. so it wasn't just a little noise. I ordered the same toothbrush heads about 9 months ago and as soon as I heard the noise I remembered that the set does the same. We ended up throwing the head away. So we broke the $8.50 toothbrush head. For the price they should all be functional and not be overheard in China while brushing your teeth in Texas. Now I go to the store to buy them.
