I don't really worry about that. I get a pretty solid attachment. Its not coming off with a little rain or wind. For me to get the thing off I gotta like soak it in warm water and work it with my fingers for awhile and its still hard to get off, cause i leave some of my hairs to stick onto it like anchors. And when I use it on my skin system,, water cant even get through the base. It has worked fine for me, and with this clear liquid the bone seems even stronger
