I can sanitize them better than any other rests I've used. The problems I've had with most of the gel neck rests, is they are only good until they get wet, then they slip off. I've tried the gel rests with the built in suction cups before. They are better than the ones without, but they eventually give way when wet as well. The major pro with this item is the suction cups are made of material that are not gel. They adhere terrifically. They are built around the gel and attached that way. I'm assuming one would want to keep that area dry in between uses so it doesn't eventually break down there.<br />The only problem I have is the single cup does not reach to the outside under the sink. Not sure if my sink has too thick of a rest? Either way, it is not made for universal use. Nevertheless, it still stays on, the single one just stays un attached. It does get caught on the chair sometimes if I am not careful when I bring the client up from the bowl. If this company would make this rest a little longer in the single cup area, it would fit most sinks, and I would sing their praises and look for a way to rate it with 10 stars!
