I have had one for over10 years,and as Marc says they are a staple at Qld AstroFest.
They are mainly used to put the computer gear in, but can store your scope in as well.
I cover my16" Dob in it.
I just lay the dob down and slide the complete thing over it rising the scope to the zenith at the same time.
My scope is 2 meters tall
The bottom on mine is removable, but different models may have it as a permanent fixture.
Yes at that price you cant go wrong.
Cheers
