[ILLusion]

TM BBs are a bit more expensive than most other brands, that's the main reason why.

As mentioned already, and from personal experience, these are great quality BBs. They're around the same size as Excel BBs, but more concentric and just as smooth finish (if not smoother.)

The only thing that I think they really fail at is crush tests... they will shatter. At least they don't crumble...
