This device is basically a small heater and a wire shelf inside a duffle bag; plug it in, it heats up. There's a timer and indoor/outdoor thermometer included in the box, but they're not automated or connected to the packtite; it's up to you to visually check the time and temperature from time to time. There's only one shelf inside the device, so it's not very useful if you're putting in a lot of personal items. The temp got up to 125 in about 40minutes, then up to 143. I'm going to buy a wire shelf to place on top of the single shelf, so that I can at least put stuff on two levels. This feels like a successful high school science project; it does the job but not much else. Definitely NOT worth $288, but unfortunately there's no other device like it out there.
