Review on QWORK Controller Adjustable Parameter Backlight by Daniel Shankle

I bought this to replace a device that has been working for 2 years. The maximum current that the previous device showed was 20A, it should be up to 30 in Okay yes? in this case no. Panels connected, reconnected to unit, lots of smoke, smell of burning and then 'pop'. Display went off and didn't work. Only 5 minutes from start to finish. Time on ammeter that I connected was 17 amps.
