I got these last fall knowing full well that when spring came they would get a work out. I always wondered how a set of these would work for my situation with my windows at home. My home has the original 124 year old wood windows that have been beautifully restored. They are protected by storm windows from probably about the 1950 era. The storm windows are nice enough and do a great job but when they need to be removed for any reason, they are heavy. My windows are 84 inches long (double pane) and some are 96 inches long. That means I am trying to handle a window at least 42 inches and they are heavy. Especially trying to keep them lined up to get them in or out. I am mashing fingers etc. A couple of days ago, I got to try these out and they saved the day for me and my fingers too. They have good suction and I was able to use one of these to help me get the windows where I needed them to be without mashing my hands or fingers. I wish I had them years ago. I will next be using them to replace a window in the garage. These are one of those tools that there is really no substitute for and when you need it, you need it. I highly recommend them.
