Super slow mo, like 240fps, is only 480p, but even if you look it up, the low light video quality is super grainy. IMO not worth the bones unless you're buying a couple of them(for different angles, using the wifi remote to syncronize them all) for daytime use.

I've trusted the suction cup many times and it hasn't failed me yet, but thats only because I've been too forgetful to bring my trustee string with me.
