I got a pair of these to use at Disneyland. They worked great. With all the channels and sub-channels, only once did I pick up anyone else (and it seems like 1/3 of the people in the park were sporting some sort of communication device!). The range was surprisingly good.
I haven't replaced the batteries yet, after about 14 hours of use. It doesn't really strike me as a battery eater.
How could these be better? With all the background noise in the park, it can be hard to hear someone talking to you if the unit is clipped on a belt. More volume would be a definite plus. And an incoming call tone would also help. Thoughts to consider if you plan on getting these to use in noisy locations. If you want them for camping where it is nice and quiet, these are great radios and all you'll ever need.
