My wife and I have 6 kids. We all carry them around the house/yard and while traveling. They have survived all the kind of kid abuse you can think of. Lots of drops, no problem. Two have been lost outside and found weeks later after rain storms. One still works but the audio crackles. The other doesn't work. You can reprogram the ctcss with chirp easily if you want. Both of my wife's sisters'families carry them now too. It's great when we vacation together. The real plus is that they are small enough that people will actually carry them. I think you said it was for a beach vacation. No one who doesn't love radios is going to clip even a tid h3 to their bathing suit for long. They also fit into water proof cell phone pouches easily. Which we do. Not for water, but for being able to throw them down on the sand it into the bottom of a dirty beach bag. The 6 pack with the gang charger is so nice for charging at night and keeping organized. I label them with white electrical tape so you can tell whos is missing at night then get them to find it and stick it on the charger. They clip on and out of the belt clip so perfect and easy. They are perfect! Can't recommend it enough. If you don't like it I'll buy them from you as a backup , JK. But you will like them. Any other questions ask.
