Only time will tell how long it will last but it was fairly easy to install and I did it without glue. I stuffed the bag in, then pumped it up until it was around half or so full. It was tight enough as I turned it to know exactly where the bump for the fill was and just turned it until it was visible and came through the hole in the bottom. I then installed the piece in the top laced it up and filled it. It has held its fill for several days which is longer than the original ever did.
