Dr. Wizard's Patented Elevation Indicator Huge Extender

Well I was really excited to get this as I had admired a set my friend had for awhile. But when I got it I found that it was really awkward to use. I bought a couple of them and some of the holes were too small, and some of the holes were too large. Basically the bases never fit right and could not be easily used. Also you are expected to attach the top with silly putty, which is ridiculous. I found out from my friend later that they super glued them together, which is probably what I am going to do. So rather than have some great interchangeable risers, I will have a couple that will always be around in different sizes, and that's not what I originally wanted. This is a really good idea that someone just didn't do properly.
