On the subject: I am impressed that the manufacturer apparently often read reviews because I have read many texts indenes was "Insufficient ventilation", "glass front must be used with difficulty" ... but in my terrarium more holes were milled for ventilation and the complete (!) glass front was delivered pre-assembled, class.
The building is super easy and is done in 10 minutes alone when one is somewhat technically gifted, but even without talent and / or with a partner that should be done within 20 minutes.
If it is then it is, it is stable and needs no additional angle, if you breed miniature elephant in there not degrees want ..;)
The glass as I said clearly exposed, scratches and in the profiles indenes the discs they run slightly to the side.
It is painted even from outside, made from inside dense and after setting up, the young dwarf bearded dragons are in it feel really comfortable even for a few months.
Conclusion is a super simple terrarium, high quality finish and for a really good price -> buy recommendation
