Well worth the money. I have purchased a few of the cheap $50 ones that never last. You know, the ones that you can use one time and then you can't even fold it up because the cheap material just breaks? I decided about a year ago to invest in a good one with the detachable side walls with windows, and it has been used many times with no issues. It is very heavy, but that's just because it's made out of quality material. It has held up well to strong winds, side walls are still in perfect condition. We love to bring this camping, our camper is small and we like to have additional space outside, this makes for a great dining area. It is well lit because of the windows and when it's all closed up it completely blocks the wind and really does seal up tight. No flapping or side walls coming undone, (even if the main door part is open, it still does not flap, the side walls stay in place very well) they fit very snug and is super easy to install as it's just Velcro, so you stick it up and it stays. Very happy that it has lasted me so long already, as a year is way longer than any other than one I have purchased. Highly recommend. Just as an idea, I would love to find some accessories for it.. like if it had an option for a screen wall where I could swap out one of the side walls for a screen version. Or if the windows had a built in screen like a tent window would have, where it could open to vent. That would just make this canopy over the top amazing.
