This is an ALL STAR commercial grade canopy. I was very nervous as it was quite heavy upon delivery, near 70 pounds. The bag and frame are much longer in storage than the EZ Up brand as well. HOWEVER, once you put the wheels onto the carrying bag, pulling the equipment is easy. The frame is made of aluminum. I chose that style. However, you can upgrade it to steel-but would be heavier of course. This is not some tin can aluminum, it is solid and heavy. There is no way it would bust in a simple storm. The canopy comes in several different colors of your choosing. Now I am very picky about my canopies and the material that goes on my frame. I don't like the paper thin product. This company has a very sturdy and thick fabric that attaches with ease! Plus you can store the canopy ON the frame after you use it the first time. Just fold it up and put back in the bag. The enclosure kit INCLUDED with this deal is made of the SAME thick material as the canopy cover. Even better it is all VELCRO to the top of the frame. How easy! They have all the sides already zipped together so all you have to do is Velcro it to the top canopy. The doorway is very nice and the window are very nice as well. The window is screened though so the ONLY downside I might post is that a couple times the Velcro sticks to the screen so you have a lot of knots in the mesh. Other than that, I would HIGHLY recommend this canopy to ANYONE looking to take their business to the next level. I'm glad I took the chance and invested.
