I get that a lot. My buddy was dubious about QRP until I got him into SOTA. Now he has a Yaesu 818 and an LNR Mountaintopper on the way.
Then there is all the shooting and reloading stuff I've manipulated him into buying. I'm a well rounded bad influence.
It's a good tuner, you will like it. I think it'll tune up just about everything. The match can sometimes be pretty narrow, so you have to watch carefully for the light to go out (go too fast and it'll be a quick blink). I only got rid of it because it wasn't needed with the KX2 and its ATU.
POTA's fun. I've done a bit of POTA myself, but I prefer the activity of SOTA. It's common for SOTA summits to be within a POTA "park" (in these case WMAs, National Forests, National Parks, and so on), so I can do a dual-activation. Because the exchange is the same, I can use the same contacts for both.
