If your ICECO unit has an available insulating cover, get it. Simply put, without the cover, our VL-60S had trouble keeping temp on hot days. With the insulation cover, it is able to get to temp and keep it, however the compressor never shuts off. It just runs and runs and runs. I give the cover three stars as it still doesn't keep the VL-60S insulated enough to allow the compressor to get a break.
ICECO must know that their units are not well insulated or they wouldn't offer the insulation cover. Think about it. I have had other portable fridge/freezers from other manufacturers, and they didn't offer insulation covers, the units kept cold and the compressors would cycle on and off, in hot weather.
