Query: Too Costly for This Type of Unit

Similar units are now very inexpensive, but still not worth the price. It seems they are all made the same and have no life-span. I had purchased a Koolatron unit last year, and 3 other brands this year. Each of them lasted less than 1 month, but I thought the next one would be better - not so. The manufacturer needs to do a lot of work to make these little cooler/warmer units something more than throw-away items.
