We like this unit

I am using this to cure resin rather than dehydrate food. I put pieces in an set to 95 for half an hour, then change the temperature to 149 for an hour and a half. This fully cures resin and it’s wonderful. There is no ‘off’ button, so to truly be off, you must unplug the machine. Pressing ‘stop’ does not stop the process, nor does opening the door. My biggest complaint about this product is that the trays are not level. They are obviously not meant for what I am using it for, so I can’t really fault it too much. The trays are a little warped and do not sit flat. I am forced to check my level on every tray every time I use it, because they will rock and ruin the level on resin pieces. I level each corner with popsicle sticks and am searching for trays I could use in place of the wire ones that come with the unit.

It's hard to get it to stay in because the directions aren't helpful, but once you figure out how to work the controls it's really good.
