Review on SEEKONE 1800W Industrial Heat Gun with Variable Temperature Control (122℉~1202℉/50℃-650℃), Overload Protection, Two Temp-settings, Four Nozzle Attachments - Ideal for Shrinking PVC, Bending Pipe, and Removing Paint by Manny Darawi

First temp. The label is wrong. "+" must be higher than the temperature and "-" must be lower. But that's the opposite of what he shows. Second, at low speed and in low temperature settings. I have 178 degrees. and at high speed I get 136 degrees. so not close to 122 degrees. They say that after running at high speed, switch to cool (slow speed) before shutting down to let the heat gun cool down, but HOW can it cool down when the temperature rises higher at low speed? I could only read 535 degrees. that's all, so I'm not sure if it will go 1200 degrees.
