the new user interface is a little hard to figure out first go,I had to consult the "paper of knowledge",which most like to think they don't need, but that temp LCD is comforting.
I got a Hakko FG-100 tip thermometer off Ebay, not because I needed it but because it was so cheap - $17 - I couldn't pass it up. Well, it's probably a "fake" but it works great. When I tested my non-digital 888 with it, I set the knob to 350 deg C.
You know what the FG-100 read?
Exactly 350 deg! Not one deg off.
I was shocked.
