I got the larger size, and indeed, it is large. When thinking of size, include the extra diameter added by the tools you store on the block. By the time you're done, this takes up quite a bit of real estate on your bench. The only real criticism I have though is that while black is a classy dressy color, it means the drill holes are black/dark shadows on a black surface. Without shining a light on the block, it's sometimes hard to see the holes when you go to put a tool back. I may end up repainting mine a lighter grey or something, so the holes are easier to see.
