Query: Kids (and adults) love it!

I ordered two sets (4 guns). The guns are great. I thought one was dead right out of box, but I switched the battery holder with the battery holder from another gun and everything was fine. They feel very sturdy, but can't help but worry about the kids dropping them. My nine year-old loves them. We play constantly, and his friends want to come play all of the time. THE GUNS ARE NOT COMPLICATED TO PROGRAM! Very easy. If you just want to start a game, pull the trigger twice . . . there is a 10 second countdown, and then the game starts, even if everyone does not start at the same time, no big deal. Excellent lazer tag system.
