Once I figured out how it works, it seemed fine, makes cold things hot, melts cheese, rarely starts a fire.  but really, how cheap do you have to be to not include a users manual?  And the only page with a QR didn't take you to the manual, or even the specs so you could look the manual up, no, it told you the number of the paper you were looking at, the same number found at the bottom of that one single page. Brilliant Holmes!  Pretty sure I discovered the gender of my range before I found the make/model info so I could find the manual to run my new toy. It looks like it can do a lot of stuff, but by the time i got to the manual I had enough patience left to set the clock and beep pattern, everything else we've been figuring out based on educated guess mixed with trial and error.
