Brushmo Whitening Replacement Toothbrush Heads Compatible with Philips Sonicare Click-on Handles, Medium-Firm Diamond-Shaped DuPont Bristles, BM664, 4-Pack, Black

I have a "big box" store branded version of the Phillip Sonicare model toothbrush. I am shopping an upgrade for that unit, but needed replacement heads in the meantime. Brushmo was actually suggested by a browser search as a cost, design, and usable option for my now defunct sonic brush. I honestly can find one negative, they are a different color than my base unit, so not an actual complaint. Since my current model doesn't have smart features or a need for microchipped and branded replacement heads, these were the perfect choice. An internet search pointed in the right direction and these are quite feasible for "snap on" or click on" models of the Sonicare design. I would recommend and obviously, the Internet agrees. 😄

Perfect fit and sooo much more economical than OEM. It won't read with the handle to show when to change it out, but the color fading bristles will do that for you. Don't spend the high amounts for the name brand stuff when these work just was well, especially when it's the handle that does the real work

Perfect replacement heads for my new Philips Sonicare 3100. I like to alternate white and black replacement heads, especially in my guest bath, so that visitors can share the toothbrush handle, The click-on brushes are easily interchangable
