We bought 3-2 packs for our family. We use them at the larger city parks so when the kids scatter we can check in with them when they are out of site. The radios are smaller so the belt clip fits nicely on the kids shorts or in a smaller pocket.We've had them 3 weeks and no problems, I would recommend them.
I must say, I got these awhile back, and they are one of the best purchases I have ever made! I always used them when I went camping, in the store with my mum, and went to the park. But they have been used so much, its time I buy a new set of these things! (I plan to be a little less abusive with them!)
