I should start out by saying that I am a physical therapist working in a skilled nursing facility. I recently had a patient that had a hard time with the nurses bell, so I decided to try these out.
I love how easy these are to use - turn the on switch and push the yellow button to talk. The clarity is great (although I have only used these in shorter distances- about 350 feet or less). The battery life has been good as well. And, while I hate to admit it, my little boy got a hold of these and dropped them several times before I got to him with no ill effects on the walkie talkie.
I would definetly get these again, for kids and grown ups alike.
