Review on ⚡ Enhanced Charging Voltage for YIHUA Soldering Station: Boosting Performance and Efficiency by John Brazington

I bought it mainly for a heat gun, I needed a spare soldering iron. I figured I could use this for most of my stuff and keep my old soldering iron as a backup. I lined up a bunch of 18650's with new heat shrink tubing, turned on the heat gun and only showed "SE" on the display and wouldn't turn on. I used it once just to put on a little shrink tubing for the wires. Maybe the heating element is dead? All is well. It happens. Ordered new, shipped the next day. I took the old one off, took readings from the heater and sensor and they matched the readings on the new one. Hmm bad. Replacing the heating element did not fix the problem. EDIT: As I was writing this I just decided to cut my losses, give them a star and move on. Yihua did everything to help me and make things right. It was unexpected. I can say that the biggest mistake was that I didn't contact them in advance about this. This is a good company and it surprised me. They showed interest in the problem and more interest in fixing it. They exceeded everything I expected. If "SE" appears on your display, contact them before engaging.
