Heater Kit For Keypads And Card Readersstar rating 5jOSEPH W.December 1, 2010we like this product but when it stopped working and called the company that makes it, they told us that we would have to send it back to where we purchased it and they in turn would send it back to the company that manufactured it. This is not acceptable. They should have taken it back and replaced it. It was under warranty. Although we like the product we would not buy another based on our experience.
