I've tried them and wasn't impressed. They draw a lot of power for only keeping things chilled at best. They don't have the power to cool things down, your stuff needs to be cold before it goes in, the cooler maintains temperature it doesn't cool. I went back to a regular cooler with ice packs that I throw in the freezer and use as needed. The ice packs are ready to go and keep things much colder, they are also easier to deal with than ice cubes. I have had three of the electric ones and the last one cost $120 and worked the same as the first one that I got at a garage sale for $5.
