My Weller soldering gun gave up the ghost and I got a Hakko FX-888D to replace it. OMG! I had no idea how bad I had it! The Hakko is amazing. Another reason I got it is because the bit shift menu display, enter button and up arrow button (no down arrow) interface reviews are so bad they are hilarious. I had to see for myself and now can confirm that the interface is "flashback to 1970's programmable watch calculator" terrible. I only use one preset, so I just turn it on and off and it performs fantastic. It was surprising that the stock harness didn't require more modification. Like it was made to go up a taller tower.
