Figured I would throw a random data point on the EasyBraid EB-9000S. It worked quite well for a day with general soldering. Up until I switched ports.
After switching to the second port with the SHP-MTZ tweezers (which worked fine), I switched back to the first port. No heating up, and the display just read "Load 00". After turning off/on to reset, it still wouldn't heat up, and started periodically displaying 'Error (22)'.
At this point I noticed smoke coming out of the unit, and a terrible burnt electronics smell filling the room.
I'm hoping they will be easy to deal with for the warranty, but I'm pretty frustrated that I only got a day of use out of it before burning out.
