Query: Mighty Mini Laser Show- Long Lasting, But Brightness Lacks

We got this for a Haunted Trail inside a "cave" with fog machines. The device itself is very compact, portable and easy to use. Has a nifty kickstand and can run in MANUAL mode-- where you change the beam and mirrors-- or AUTO-- where the unit itself loops through a pre-programmed show of all its different effects. Runs on 2-AA batteries that lasted well over two hours set on full AUTO. My biggest disappointment was the brightness. It looked quite cool through the fog, but wasn't very bright considering we were inside a "cave". Other than that, I was very happy with it and will use it next year.
