No, I have never heard of it, but I think it may be just in the UK. I went to google and searched it and it looks okay, but I think you would be better off buying it all separately. I saw some repti-sand and a really small water dish. If you bought it all separately you could pick and choose what you want in the cage.
Here is a good list to start you off:
10-20 gallon viv with good top.
UTH heater that is made for the size viv you have.
Substrate-aspen, or another kind of snake bedding. (No Sand)
2 hides that are big enough for the snake to be totally in.
1 large water dish-preferably deep.
A digital thermometer with a probe.
And most importantly a snake. lol
Hope this helped.
