Huh, I clicked on this expecting it to be a blatant healthwoo scam. ("igienizing"? come on.) And it basically is. Their antibacterial liquid choice seems uninspired and I'm not buying a funny shaped squirt bottle for €70 .
But price tag aside, the bracelet concept itself looks pretty clever. Conveniently always at hand, expect it will get more regular use than carrying some sanitizer in a pocket or on a carabiner.
