Stefan, I have used it.
Take a look at the link.
Uromastyx - Terrarium
This are "old" pics from when a pair of Uromastyx ocellata were in it.
This is our old fireplace in the livingroom.
In a few months I will place my T. sirtalis tetrataenia in it.
The colours are different now and when it is ready I will place pics here.
