This is a good light duty shelter. We have an acorn problem here for 2 or 3 months in the fall. The oak trees here are very tall and if you have a wind storm, which we have often, acorns can cause a lot of damage to our 3 cars and has in the past. I orginaly used the tarms that were included but the wind storm wreaked havoc with them. Now I just use fine bird net instead of the tarps and that works great. These have holes on some parts that don't correspond with holes on the other parts so I drilled my own. Plus I added metal screws in various places as in the fisrt wind storm with the tarps it pulled apart where there was no screws or bolts. Other wise I'm very happy with these, I have 3, they do the job and look good.
