I have the turbolaser emplacement one, and it's a solid brick of resin. Obviously it's going to break if you treat it badly, but if you're reasonably careful with your models (as you should be) it's no more of a concern than any other model. As for the warping, mine seems to be pretty flat. I haven't started working on it yet, but it passes the eye test so any straightening should be pretty minimal.
(Note that I got it as a photo backdrop/diorama piece, so I haven't tested how it fits with the other
RoB tiles.)

Strongly disagree here. Unless you're an absolute god of scratchbuilding you aren't going to build anything like the
FW tiles without an immense amount of effort and probably a lot of money. They're really nice display pieces that you can play a game on, not the usual tabletop-quality terrain most people use.
