I've tried the Team Checkpoint soldering stations which is a relabelled Hakko 936 I believe and I keep getting the iron melting off of the handle. I had it happen the first time, so then ordered a replacement iron and same thing happened. So now it sits unused and I've gone back to my 60W adjustable Radio Shack/Princess Auto (Chinese made probably) soldering iron and it works great

It's not just me either, I've a buddy with the same station and same thing happened to him.
