All though this item may appear cheep in price it's a very good walkie talkie.Light weight,good readable display,lockable keys,so if you have it in a pocket it will not flatten the batteries.Runs fine of re-chargeable batt's.When used with the head sets in "Vox" mode,they need no setting up or touching once you have found and set the channel.Being a "PMR",you can have multiple sets all talking to each other,I personally have had 8 radios all working together whilst on an organized walk.Quite robust to,the kids used them as toys for 2 weeks in Spain,no prob's. I personally use a set of 3 in my job as a Motorcycle Instructor,and have ample range even in built-up ares,(about 2Km),but upto 3 miles on open fells.
