I have one the thing is that it does fit a FSLIC statue that is 12" or less such as the retro, modern and x-factor cyclops, the avengers base hawkeye as well the new ultimate captain America and the action juggernaut. So far but no hulks or new rogue or the new action Spider-Man and certainly no gargoyle daredevil or museum ironman statues. Hope this helps you.
I have one and only certain ones will fit. I've had Ultimate Cap, Venom (crouching), classic Cap (museum) and a few others in mine at one point. I've noticed a few of the museum BD statues w/ short bases, Kotobukiya action statues and Hot Toys fit really well in these. Dusting is a b***h though!?
Here's a shot of my messy display from months ago (sorry no Bowen's in it though):
