Well there's a big ass RTA on top of it, so it would be tall. I personally don't mind though, i think it actually looks pretty awesome (although i don't have the ultem tank piece). Sucks, because (and i know i won't make friends with this now) i do think that £100+ is extremely steep for a piece of plumbing with a button on the bottom. That being said, i never owned a mech, so maybe there's a reason that i can't see subjectively.
That does look good mind. I'll watch reviews later, just briefly: a rather short, or a rather long throw on the button, and is it soft or "hard" to press?
edit: wait is the ball bearing the fire switch?
