I bought one of these radios a couple weeks back for use out in my garage.
For what it is, it's not a bad little radio. I don't think it will win any awards, but if all one is looking for is a radio to hit the local repeaters, or do some short range simplex, this radio will fit the bill.
Mine works decently out in my garage. The audio volume is pretty good for the tiny speaker it has, and I have no trouble hearing it. I've been told my TX is a little muffled, but not to the point of not being able to be understood.
My only gripe is that it randomly turns itself off. At first, I thought I had the auto power off function turned on, but I didn't. Sometimes it will shut off after just a couple of minutes, sometimes after 15 to 20 minutes, and if I get lucky, sometimes it won't shut off at all. Ah well, no huge deal; it's only shut off once while transmitting. All other times have been when receiving.
