works great!
These work over a longer distance than I thought. My dog was lost in the woods and I had to use these to communicate with the rest of the team, it worked very well across a broad mountain range. Will try these on an upcoming cruise as well (will see if I can even take them.) but should work fine for that purpose as well. Overall, found my dog and still kept these because they are just too good to return. Very good quality - even after dropping one down a hill a few times.
I was a bit skeptical at first but after using these now for the past 4 months kayak fishing, I am very impressed. Good sound, good range and so far very durable. The batteries last a long time per charge. These are way better than my Midland and Motorola units I have previously purchased which dies fairly early in their life. I suggest you get over the price skeptical hesitation thing and buy yourself a set of these radios. I'm glad I did!
Excellent Walkie talkie. Use them for Jeeping and most recently working on our sprinkler system. One person was in the basement and one was in the yeard- worked perfectly.
