Excerpt: Radio is great for any outdoor activities. 23 miles is more than enough. I tested the radio in low power mode around the neighborhood (urban) and works fine in one mile radius. Very low power usage, days on standby mode. Great radios for the price.
Pros: AA Battery, Low power usage, Power Setting, price, Usb charger
Summary: My wife and I purchased these radios to use while photographing wildlife. The radios had to be able to operate quietly, with no extra tones or sounds that might startle the creatures we were trying to photograph. These units work very well for this purpose, and the voice quality during transmission is excellent. The confirmation alert can be turned off, and the volume range is such that we can communicate in whispers when necessary.
Summary: One radio could not turned on. After I exchanged and tested the second package in store, I found the same problem. Future Shop's sfaff told me it is the manufacture's problem. They put one good battery pack and a bad battery pack into each package. It wasted me too much time!
Summary: If you put football fields end to end, you might be able to transmit and receive the advertised distance. Otherwise, if you want to transmit and receive, do it within about 2 hundred feet. They will work that distance. Disappointed with the distance of transmissions.
Summary: I purchased 5 sets for work. 3 of the 5 sets failed to keep a charge for more than a couple of minutes. 1 set will hold a charge for a work day. I set will hold a charge or nearly 1 week. The charging cords are tethered together and require a usb port to charge making it difficult to charge. These units are used very lightly during the day, but seem to be almost unusable as they cannot be relied upon to hold a charge.
