I really like QRP Guys kits and designs. I've built several of them and they generally work as advertised.
My complaint with QRP Guys, they have never responded to my emails over the last couple of years, including the replacement of missing parts. I realize they're a small operation, but they do take our money, so someone should be responsible for answering emails and definitely replacing missing parts.
I'll still buy their kits knowing I'm on my own if I have problems with them.
