Purchased this as an overland unit, after receiving, I plugged it in to test it,it holds on to the temp really well for the first 2 days so I lowered the temp and loaded it with some items in the freezer -8 and was keeping things well frozen. It was actually doing a good job that I have it hooked up for 3 weeks until we cleared out some items in the regular freezer.CONS - , I noticed that the internal temperature is easily affected by the ambient temperature. It will benefit a lot with an outer jacket for additional insulation. The latch does not look very sturdy and needs additional care in opening and closing. The display looks like an old LCD unit and has a backlight that is constantly on. I wish I can turn the backlight off coz it looks like it might kill itself prematurely like the LCD of yore'.Other than those complains , this looks like a stand up unit. a very good price point. I highly recommend it vs other units out there, now for longevity?!? that is a wait and see situation.
