I really like the design of the safe top lids with the large ventilation holes to prevent sweating.

I haven't tried their product myself yet but it's on the wish list!
I've got one, no condensation at all. It's been on the tank 6 months or maybe longer, no sagging, bowing, or any issues at all.
On a previous tank I had an Artfully Acrylic and it was ok, but the condensation on the solid frame was pretty annoying.
