I baulked at the price, $130, I don't think I'll bother, I have a compressor fridge now but may just keep the other one for gas on long trips, it did keep things cool on hot days as long as it was in the shade
I've never progressed up to an Engel .... yet ....let alone one them new fangle ones with electronics that break, level na you worry to much look at its guts, you soon work out one way is more critical than the other.
Yeah true some have become less reliable with all the extra electronics my digital Waeco stuffed after 5yrs but my 17yr old Evakool with the thermostat dial still starts up and runs well just like my 71 model cruiser.
drive, 12volt on ... no thermostat, nothing but on or off, freezes milk in that corner within the first hour, note to self put milk in opposite corner, 240volt, same no thermostat, again on or off, gas >>>> yay a thermostat, note do not go past the drawn on mark or beer freezes.
