Love the toothbrush! My only concern is the handle gets very slippery when wet. I have had hand surgery and find it difficult to hold while brushing my teeth. I have dropped it several times. And I broke my previous one, it landed on the head and stopped vibrating. I wish you would wrap the handle in silicone. Right now I have wide rubber bands around the handle. Not a good look.

I like the tooth brushes they clean well but they only last me about a month and I have to change them out. I wish they lasted a tad longer. Maybe I'm brushing too hard.

I have a Philips Sonicare 6100. I recently purchased a 5 pack of replacement brush heads. Both my wife and I find it very difficult to attach these to our handle. Then when finished, it's very very difficult yo remove the brush head from the handle. We're afraid we're ging to do damage to the handle, Did I order the wrong item? If so, please let me know what I should have ordered and if I can return the unused brush heads that were ordered in error. Thank you.

I bought a 5 pack and every single one has had at least a couple of bristles come off in my mouth . . . usually stuck between the gum and tooth.

I would give this zero stars if I could. Have had Phillips sonic brushes for years. Most recent one was a HealthyWhite. Bought two packs of the C1 brush heads (not cheap) and they don't mount properly on the HealthyWhite. Started rattling and leaking brown oily fluid from the head. Decided the problem was the handle so bought a new one (Protective Clean 4500), and these heads are even worse with that! They don't fit on the handle unless you push really hard, and then you can't get it off. One head even separated because splitting the brushhead shaft took less force than removing the head from the handle. Gave a brushhead to our daughter to try on her sonic handle and it didn't work for her either - rattled and wobbled. We have been through several brush heads in the pack and they are all the same. The package says these heads are compatible with all Sonic toothbrushes but this is simply NOT TRUE. Now we have two handles (presumably the first one still works) and no heads, and no idea which replacements to order that will work.

Back of package describes the bristles as "extra soft" rounded bristles sensitive on teeth and gums but the front of the package says its a "medium," which are not sensitive for teeth and gums.

After loyally using multiple Sonicare products for years, these C1 SimplyClean heads (HX6015/03) are big disappointments. The metal mounting ring inside the plastic head detaches after about 2 weeks. This has now happened with 2 heads from the same package. If you start to hear an unusual vibration while brushing, it is starting to happen. Before it self destructs, however, it does work very well.

Great product. The blue bristles let you know when you need a new head.

I have two different shafts and these brush heads come off while brushing using either one of the shafts.

The tooth brush heads do a great job getting my teeth cleaned. The bristles are not to soft or to hard.
