I can't wait for this one! I'ts the perfect size, almost invisible. But it'll either need to be released with magnets or be so cheap I can justify the hassle of rigging up a holder for it, or my own magnets, since I can't even get a veggie clip to stick to my glass with all the years of coraline growth! I wouldn't trust a suction cup for anything in a reef that's been going for more than a week.
