Review on Superior Cross Action Replacement Toothbrushes for Optimal Dental Care by Katie Garcia

I've used Oral B heads from time to time. Compared to Walmart's own brand, they were better and lasted longer too. However, these turned out to be even better than Walmart's and cheaper too. They seem to work well and seem to last just as long. I'll need another month to be sure but I'm sure I'm a little shy of two months due to their use. A word of caution: in the last week or so the very first one I've used seems to have loosened up a bit because it seems to detach from the main unit when I put a little more pressure on my head while moving up and down. Not sure if this is an isolated issue or if I run into it with others, only time will tell.
