Not great
Color: Black, Size: Wheel-132''
The product arrived and in good condition but I can’t assemble the tube A to tube B because i still have to deburr the inside part of the hole. They did not clean the drilled holes.

Almost impossible to assemble 😞
Color: Beige, Size: Wheel-22''
Took 2 people to stretch the fabric out, to connect to the poles, and the side bars did not match to the holes that you push/slide together

Do not buy this!!
Color: Black, Size: Wheel-132''
The holes to assemble it together were in the wrong places and it was welded together, so you can’t move it around. I’m not able to use this.
