Cagesbydesign cages- Good or bad?

I am just curious as to if the reptile cages made by cagesbydesign.com are any good.

Will the cages hold a good amount of substrate?
Do they hold humidity well?
Will feeder roaches escape?
How durable are they?

Just in general if they are actually worth their reputation. I am looking at the H3 model, if any one has ever or does currently own one. You do not have to own the same model that I am looking at, I just want your opinion on these cages before I put out the money.
