I've been using that radio for a while. It's not bad. The roller/enter/select button is annoying, but otherwise I like it. I don't use it with any receivers that have sensors or anything. It's nice not worrying about busting of an antenna or having it unknowingly stick up in a chest camera's footage.
I put a receiver plug jack on it and wired in a 2S lipo to that jack, then made a receiver->2s charge adapter for it. The thing seems to last forever on a charge now vs even LSD NiMH's. Would have been useful if they thought about that a bit and let you set the alarm voltage for a lipo, but since it's on the screen, it's easy to pay attention to. I charge it up every 3 or 4 bash sessions.
I did goof up something inside though with the power switch. You don't click it really, just touching it turns the thing on. But that's my own fault. lol!
