Toptheway Replacement Toothbrush Heads for Phillips Sonicare DiamondClean Protectiveclean 2 Series Dailyclean Plaque Control Electric Toothbrush 4100 5100 C2 C3 W2 G2 HX9023, 8 Pack

To guarantee fit these Toptheway brushes were tested on three different models of Sonicare handles and all were next to impossible to install (push on) and remove (pull off). I was fearful that I might damage our expensive Sonicare with an improperly designed $2.00 brushhead. My wife was unable to force this brush on her Sonicare. It took 11.8 pounds of force to install and a similar force to remove. Toptheway states their design is fully compatible with Philips Sonicare Snap-on brush handles. Toptheway brushes DO NOT Snap-On like Sonicare brushes do. The brushes are held in place by brute force friction. Folks, this is not the way a properly designed brush should fit. Toptheway failed in dimensioning and tolerancing and/or forgot to take plastic shrinkage into consideration when molding the brush body. How could a company advertise and sell a product that is so poorly designed? A properly designed brush should easily snap in and lock. Please look at my attached photo as it clearly shows the force to install 4 different brush head designs on my Sonicare. By comparison you can see how cheap the 2021 Toptheway design is. My latest purchase was the WEQNNM which works great. Sadly the Toptheway brushes sold in 2020 were high quality and very much like the OEM Sonicare brushes. Toptheway decided to increase their profits and go cheap in 2021. The Toptheway brushes went in the trash. Thank you Amazon for my refund.

These are just ok. I’m glad it is a multi - pack because the brushes don’t last long. After the first time I used one the brush hairs started coming out. I’ve had to trim them down every week or so; they don’t last as long as the manufacturer brand. I have a soni-care. They do the job and the price makes up for cheap construction.

I was under the impression that these were medium firmness...but they are super-soft... :(

Thought these would be great, turned out to be worthless. They lasted about 5 to 7 brushing before loosening up and falling off the toothbrush. Thought it might be a fluke, replaced it, same thing. Hated paying for the originals, but these were really bad. Ended up throwing them out to avoid any more frustration. Don't waste your money on this brand.

I got these for my Phillips sonicare C2 toothbrush. They fit perfect. I feel like these clean my teeth better than the heads that came with the toothbrush! The covers for the toothbrush heads are a tight fit but I don’t mind, means it won’t fall off. They even fit my roommates toothbrush so I gave a few to her. Great value for your money, one pack can probably last all year.

This set fit snug and well, and brushing head is nice on my teeth and gums.Bristle tips are cut very well, and works well cleaning each day.I don't see a point in buying OE Phillips tips at 5 times the price, for the same money I can use a fresh head 4 more times with this.

great value

Other people complain bristles fall out. Mine have had no such problem. The head is not flush with the main part of sonic care but works fine.
