Measuring was the hardest part of the process, but once that was done, it's been easy. Installation would have been easier if I had help, but I actually did it by myself and it was fine. We've had a fairly cold winter for us, so I was very glad to have my inserts in before the first cold snaps! It's obvious the materials are very high quality and should last a very long time. I'm very pleased with the Indow inserts!
