Review on 3-Pack of Genuine DiamondClean Replacement Toothbrush Heads by Philips Sonicare - White, HX6063/64 by Lissette Molina

One of the three heads is defective next to the connecting part. When the toothbrush is turned on it makes an awful noise but the other two don't. I just throw out this bad one because I definitely can't stand the noise for the whole 3 months. I've seen the same problem mentioned by other customers, so apparently it's not my own problem. Also, I usually think AdaptiveClean heads are better than DiamondClean heads despite being the same price (on the Philips website). So don't buy these DiamondClean brush heads if, like me, you're already happy with the AdaptiveClean heads on your brush.
