I have been purchasing from Shelter Logic for several years (3 canopies during Covid-19 to the present) and the delivery is prompt, the canopies and covers are great!

I keep my Ultra Max up year round. It holds the snow load, stands up to wind storms. It’s great! It’s like a permanent building for me.

We have been using these covers for over 8 years. one of which we leave up from April to December, it sees all weather conditions. We average 2 years from one before a leak or two shows. Unfortunately, one of our 3 tents is in the need of a replacement cover asap as we open for the season and there's none to be had anywhere. I understand the covid and supply chain setbacks, but no waiting list? "check back next month" isn't the answer i want for an almost 600 piece of plastic. for that one reason its a fair product... but buy 2 because you will want a backup you can depend on!

[This review was collected as part of a promotion.] I have this canopy in use 3 or 4 seasons and just replacing the top for the first time. Durable ans strong.
