Reptile Basic Enclosures

I purchased (2) 2x3x1 Reptile Basics enclosures with LED and heat kits about a week ago and was curious if anyone else owned this brand. Specifically, I was wondering if the ventilation is adequate or if we need to plan on adding additional vent spaces when they arrive here. Also, are the pull down acrylic doors convenient or a pia?

I looked at the Animal Plastics enclosures (I prefer their sliding glass doors and the 15” height) but, due to the 5 month lead time and non-existent customer service (they never responded to my inquiry- a common complaint according to the net), I decided that Reptile Basics was the better choice (they responded in less than 12 hours, quoting a 4 week lead time).

If the (2) units work well, we plan on purchasing 10 more (2 columns of 6 units each) so any insight regarding their units is most welcomed.

Thanks!
