My dad had one for years and i remember it sitting in the garage for probably over 20 years in the same spot and i remember him saying that it probably doesnt work anymore. My dad passed away in november and today i decided to take it out and test it and see what it would do. I had to wait for it to warm up but it worked good. My dad was probably looking down saying its about time he plugged it in. Now i have it in the house and going to put it up nice and away from the cold. He would be proud.
