I have only seen one to date it was a top opening version. I didn't think too much of it, the person had it an a shelf and the top opening was a pain. He had to slid it off the shelf to clean it or remove the snake. It was made ok just not well thought out system. There have been a great many companies building enclosures for a long time and changing the base method of how to do that is an interesting experiment but not super easy to deal with. They also have a number of all clear enclosures that maybe great for a show but nothing else the common belief is that closed sides are better so spending top dollar for something that will need you to cover the back and sides up on is not very useful. The 'showcase' version is about the only real choice of their offerings. I think it is too small for an adult The base formula I use is the width and the length added together should be about the length of the snake. It the showcase enclosure that is 3 foot 6 inches, that is not a very big adult. I have a two year old female whom is 43" and a male that is 3 whom is 50. My biggest female is just over 6 foot and there is no way the smallest hide she fits in would fit two in this and forget the water bowl.
Are you in Canada? look at SLY plastics the site is a shambles but Sylvain is a great guy and makes great enclosures for a bit less cash.
