OK I finally got this and did some quick playing around with it.
It came preloaded with 400 calls, most sound very good, of course I'm only going by what I do with hand calls and the few electronics I've been around quite a while ago. There is a back-lite night glow green color on both the hand remote and the caller itself, very visible in the day.
The caller itself on high is loud, and I don't think the base was necessary, but hey it was cheap so what the heck. I walked around the corner about a 150 yards with a house and trees blocking line of sight of the main unit and no problems changing the call and I could hear the calls even with light city traffic in the background. It supposedly goes 250 yards but I didnt go that far. With the base on it was ear ringing loud on some calls up close. The call uses 8aa the base 16aa. I just used ever readys as that is what I happen to have but I'll change to rechargables later.
Its pretty solid
Now for the dumb:
The battery pack on the main unit didn't work, they had not crimped the + bracket rivet on tight enough, and the metal used in the rivet was not very metal conductive, so I soldered it and tightened the rivet. (it uses a 9v battery bracket) It says its "weather proof" but I can see water could get in through the battery door. (I'll seal it with foam)
The 9v connectors on the lower ranger unit are not long enough to "easily" get them plugged back in. Really stupid design. I'll be adding an extension of about 6" to the cord.
I can't wait to get out there and see what it brings in.
