In reality herb user grinders can take quite a whacking about. (So I've been told I dont think even digital scales can take that much usage without going out by miles even if you tare it each time. Also it would get really sticky overtime as herb residue built up around the inside between the chamber and the surface of the scales unless you cleaned it out after each use but is it waterproof? looks like its meant to have herb kept in it for all the time with that little window on it. Would be better to have it in just 2 pieces with the top that comes off only just my pov but I guess that means you dont have to clean it.
