Used it on a pack system found it very good. You have to wear the yellow specs is the only down side.

We use it on pack systems and I always find that the battery is always flat when I go to use it. :(

Also when it`s put it some people tend not to be to careful and splash the dye around, which of coarse they wipe up but it still shows up under the light (if it works).
