Amazing!
I've been using these for the past two years. We do a big Halloween party and go crazy on the decor, but it's a tight space. These have been great to control the lighting in tight areas and pin spot props without over lighting and mudying light sources. Most of the other options on the market require wiring, which takes time and if you don't know what you're doing, can be dangerous. These are pre wired, plug and play, and the housing is top notch. Would definitely recommend to anyone, whether you're doing a pro show or home haunter. These prices are low for the quality you get.
