This one (that we just cut - see "I cut more cover into fours" thread) is brand new. We killed our last one by leaving it out of the pool and sitting in the AZ sun when the pool got up to 106 degrees. Dumb move...lesson learned: dont leave cover out of pool in the sun for a month. As a result, I cannot give a lifetime test on it...all I can say is that it works VERY well. If it only lasts a year (which I doubt) the $120 is more than worth it. Aquasuperstore is also on eBay and has a bunch of good feedback on the Magni Clear covers.
