I purchased this unit in mid November. The first time I tried to use it, it failed. And yes I did read the manual, it worked for roughly 3 maybe 4 minutes and quite. I checked the fuse in the back and it was still fine, tried a different plug and it still wouldn’t work. I could hear the fan running, but the machine did nothing. I filled out a service form, I must say, never had to take a video of a machine not working before. Customer service was a joke, will not be purchasing any thing else from VEVOR
