The end covers were a little tricky to install. Slightly more fabric to wrap around the tubing would help installation and allow the fabric to reach the ground. When tightening the strap downs with the ratcheting device, take care not to pull the strap through the sleeve as it is time consuming to re-thread it. Also, if you need to loosen the strap for adjustment, the ratcheting device is difficult to release, although I did manage to get it done. Patience helps. Once set up, the shelter is solid. I'm satisfied with the purchase.
