We own various models, 2100, 3100, and the 4100, the vibration is perfect, quiet and cleans well. My 4500 is loud, vibrates super hard, tried all settings, I hate it, worst tooth brush.

Sonicare I have been a Sonicare customer for over 10 years and this is the best model. Battery cycle time is excellent, the ergonomic design is easy to hold and comfortable to use.

Different to what used to, but like it.

Great valvue.

We purchased these on Sam's Club deal day ! They work amazing I am so glad we purchased these! Deep clean your teeth! Pulses if you put to much pressure keeps your mouth healthy and safe. Charges fast! Definitely recommend especially since it comes with 2

Bought the pink and black set. The top where you attach the brush head fell apart in less than a year on the pink toothbrush. Bought another set. Same thing happened. We are not pressing down hard when we brush our teeth. Awful quality. Won’t buy another Sonicare product.

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.

Just used my new Phillips Sonicare toothbrush for the first time and all I can think to say is this: brace yourself. It was like having access to archaeological descaling tools, except for my teeth. Usually the only time my mouth has ever felt this clean previously was after my 6-month deep clean at my dentist. Wish I’d gotten one sooner

On the backside of the toothbrush head there is a small circular depression that irritates your lips when it passes over them. So much so I ended up buying cheaper brush heads only because they don’t have that depression. I can’t even buy Phillips heads now because I’ve noticed they all have it. Disappointing.

Bought this 2 pack, and the first unit I used did exactly as advertised, however, the second unit does not charge and has a weak pulse whenever you attempt to use it. If the second unit worked this would have been a five star review. Disclaimer, I am not sure if I simply purchased a defective model.
