Question: Does this canopy have a vented top?
Document: The second time I used it, it totally collapsed--frame was 100 percent trashed. The design permits rain to accumulate in the top, which bent the frame-snaps to attach the top were off center best as I can tell. I was set up to do a craft show; had to drive home and get my old EZ-Up, which I've used for years through rain and wind. Contacted the company--NO WARRANTY!! They said it should be taken down in rain and slight wind.
the quality shows in the minor details of this canopy. awesome product well worth the extra price. well planned carrying bag with shoulder straps to transport backpack style. sturdy yet light. this will be the last canopy i'll have to buy.
My family's use of a canopy is primarily for weekend sporting events and family outings. So, after enduring a "bargain" canopy, which looked great in in the store...and then self-destructed in practice, I now value a canopy that "just works" and doesn't become its own weekend project. We've now had our Undercover canopy for almost a year and a half--and it delivers!The canopy and its bag are well designed and are easy to use. Even the instructions are well-written.
The canopy fabric is far superior to bargain canopies. But, the frame is an amazing work in aluminum. A primary, unseen feature is the internally reinforced aluminum beams, which allow the frame to be very rigid. The canopy is fairly heavy package (55 lbs. in bag). But, the well-designed roller bag helps make moving an easy task. The bag also has sturdy handles (in the right places) and backpack straps. The included leg covers, serve to dress up the canopy.On two recent beach trips, we quickly popped up our canopy, anchored it, and enjoyed no-hassle shade.
I took no small amount of pride in watching our canopy remain rock steady while other canopies were manhandled in the wind.While cleaning up after the last beach trip, I noticed a *possible* issue with a button/lever on one of the corner sliders (it worked fine...but, looked like it could become a problem). So, I contacted Undercover. With neither hassle nor delay, Undercover's support team cheerfully sent a replacement part. Undercover's excellent service and communication further confirms that Undercover is an excellent product from people who are passionate about providing quality shade.Something a little unexpected: Because of its great walk-under height, the stowed canopy is longer than others you may have seen.
Well, I've had mine for about 1.5 years now...Used about 6-7 times... 2-3 in the rain...1 heavy rain.. but never very windy so I can't speak to high wind. First, it does go up and down with one person but you can cut your time in half if you have 2...works as advertised. In terms of quality, I can speak to the cover material and frame- both seem very very sturdy.
The cover is thick and has held back the rain with no problem (with no poools forming)..and of course the sun. The frame seems perfectly fine as well. It comes in a very sturdy carrying case with wheels and even a harness to use as a backpack...Why on earth anyone would want to hoise this monster on their back is a bit beyond me but its there. The wheels work great. The *only* downside is the overall weight- I did read the review of the 70 year old person but if you think you need to move this up and down stairs and have back trouble or no help, i'd consider a lighter weight version.
So why do they call it a professional model?? You can't just fold up and leave when you are doing a show if you are a professional! Offered a rebuilt frame for almost $169! Definitely do NOT recommend! !
Set up was easy. All if the parts are sturdy. Haven't had the opportunity to see how it does in rain or wind yet. Am optimistic.
Purchased with windy conditions expected. Performed as expected. I figured hat he metal corner legs would be a bit more robust, but they did ok.
