I second all the positives here. Not sure if I've read anything yet about a weak link: the drum latch. I lost a couple of pounds roast midway before figuring a way to better secure the latch so it wouldn't open up on its own accord. To the Behmor's credit, the machine stopped rather than continuing on some errant roast sans revolving drum. I have to assume that Joe's having this beefed up for the next version (along with the less than friendly stickers that secure the doors and such for transport.
Everyone should be aware that the engineers built in a safety feature preventing the machine from roasting if it's below (I think) about mid 40s in temp. Joe wrote me that I only needed to bring it in from my freezing porch for a few minutes before roasting. Sure enough, no more Err message. Something to do with needing to avoid moisture build-up from too cold a temp straight into the roast.

I got a Behmor 1600 for Christmas and so far I couldn't be much happier with it. It works extremely well (but I'm just resting my first roast right now, so take my opinion with a grain of salt). I have noticed that you need to be paying attention while fastening the drum latch as it's possible to have it not latch properly. It's not a big thing, but I've already made a mental note to pay attention to it.
As for the safety feature that prevents roasting at low temperatures, I did a dry burn in roast yesterday at around 40 degrees. Today I did another burn in roast and my first roast of 1/2 pound at around 38 degrees. The roaster didn't show any signs of shutting down due to the cold. I did hear a mild bang at one point which I'm guessing could have been due to metal expansion because of the heat. It didn't seen to affect the operation of the roaster. I was concerned about the cold affecting the roasting time. On another forum I was told that the roaster wouldn't be able to roast at temperatures like mine, but my roast seemed unaffected. It hit the first snaps of first crack at 8:40, first crack peaked at 9:30 and ended at about 10:10. 2nd crack seemed to suddenly erupt at full force at around 10:30 or so and I immediately hit cool at that point. For what it's worth, I roasted 1/2 pound of a roughly 2 year old Guatemalan Huehuetenango I wanted to use up. The settings were at 1lb. (thought I might need extra time), P2 and B. Because of the 1 lb setting, I don't think the roaster ever got to the point in the profile where it cut power to 60% or 70% (whatever it goes to), so the roast was essentially at P1.
If the concern of cold temperatures is for those that store the roaster at the cold temperatures and then turn it on, I keep mine in my bedroom closet and take it outdoors to use it. That short cold exposure may mitigate the condensation problem you mention. Unless it makes it worse.
