I use a home-brew Z-match tuner with my QRP radios - very similar to the kanga products design. It's reliable and has a switchable SWR indicator. It's slightly bulkier than the QMX but its versatility more than makes up for that. If I were buying something, I'd go for the ATU-10 or the Kanga pocket transmatch.
Popping the QMX into SWR measurement mode (under the Hardware tests menu) ensures its PA is run at much reduced output levels and offers good protection while tuning.?
