I bought this about 2 months ago, and have been pleased with my purchase. They do get our teeth extremely clean and shiny. I have sensitive teeth, and have had no issues with increased sensitivity. I have not yet had to replace the brush heads, but find that the price here at Sam's for replacement heads is significantly less than at my grocery store, so will be buying those here as well.

Exceptional value with the high quality and performance excepted but without the bells and whistles never used anyways. Love only having 1 option rather than 6. I just need to brush my teeth and not wonder why in the world I ever need the other options. Very pleased.

Been about 3 weeks so far so good. First time I used it my first thought was " feels like just got a cleaning at the dentist " but didn't say anything till my wife said same thing a couple days later. Am wondering why the user manual with it is a 6100 model when it is a 4300, just hope it's working as well 6 to 12 months from now thus why I got the insurance for it.

only one of the two works

My teeth feel professionally cleaned every time I use it!

Much lighter and smaller - easier to use

This is a fantastic toothbrush that holds an amazingly long charge.

They work very well. These are the second set of toothbrushes.

Love the adjustment s one can control

My wife needed a new setup and Sam's had a good one by Phillips.
