i have a maze4 with a clear top, and a spir@l with an alum top. I plan to open up the spir@l soon so I can try to roughen up the insides with whatever method of destruction strikes my fancy
if the maze4 ever looks like its collecting something i of course will open it. both have some kind of allen wrench top it looks like and I bought the one from dangerden so opening shouldnt be a hassle.
