I bought this for a recent camping trip- couldn’t use so we found they are a waste of money. Some of our issues were- Black one won’t work with rechargable batteries, we found three would not turn off we had to remove batteries. Blue would not change channel! Nothing but but the torches worked. We gave up trying to use as the red was only one that worked anywhere close to as advertised. We had more fun with a pair of toy walkie talkie on a previous camping trip!
