That would be interesting info - can you find out about SWM8 and SWM16 "expected" max temps please?
I'm trying to track down info Re: temps. I know mine runs what I'd call a little hot but I haven't done anything with it in months and it's doing just fine. Not sure of a good way to test the temperature on it.
A contact thermometer should work, and even some of the higher end meat thermometers. Just don't stick it into the SWiM to find out if its fully cooked.
