Managed to get one of these for under £100, and it was an absolute bargain.
I sometimes use my girlfriends Sonicare Flexcare+, and I also own the Colgate "Omron" A1500 clinical toothbrush for home, which is my regular toothbrush.
But nothing beats this. Bought this as toothbrush to have at work. I would have taken it home and used it as my main one, but the carrying case with USB charging connectivity means I can charge it at work from my computer. Noticeably the best toothbrush. Am a huge fan of the Sonicare series, and am very pleased I have been luck enough to get one of these.
