We bought these to cover a different brand of ice cream dipping cabinet. They work well. They help keep the cold air in and shorten the operating time of the compressor during times we are close. This has reduced or electrical bill not only for operating the dipping cabinet, but also our air conditioning cost since the compressor is not pumping heat into the air. We initially bought 2 to try, we ordered 4 more for our other cabinet soon after testing.
