This is an excellent product, in keeping with the quality of the Panasonic toothbrush that it is designed to go with. One small reservation (not the fault of Healthcare4All) - it would be helpful if Panasonic could have ensured that the model number of the head matched the number of the toothbrush itself. I had to contact Healthcare4All to find out which head I actually needed. Thanks for being so helpful, by the way!..
