When buying a product like this you can't mind the glass safety that goes off if you overload the unit. If you want automatic safety's you can spend your money on a more expensive device, or use your brain and buy this. However, I use this for analog stage blinders and par cans and it works great. The following remote is perfect I you rent it out with some cans to a small band that doesn't want the trouble working with DMX. It's perfect and feels solid, it can be used for many applications. I really like it.
