Our first time using it was at the beach. It worked pretty good. It fell on us once but we got it working. I'd buy it again.

This beats my red sport umbrella hands down. Light weight easy to put up. I purchased this as used in December 2020 for $87. After looking at all the different manufacturers and prices all over the board I realized all are made of Lycra. Some have cords for the sandbags some use Lycra. So why spend $160 vs $87 or $119 (current price).
Bottom line this works. We had 15 to 20 mph wind and it held up. The first day I stretched it and it-was flapping slightly in the wind. I was afraid I would rip it if I stretched it further. Next day I REALLY STRETCHED IT. And it didn't flap in the wind. Make sure you fill the bags to the max. Even fully filled the bags will move inward when you install the poles. Grab the TOP section of the poles not the middle or the bottom to prevent breaking or bending the pole and place 1-1 1/2 ft. from the corner. Then push the poles vertical. Easy for one person to put up. I found it easier to install the bungee around the ball when the pole was chest high and then put the pole vertical.
I was concerned about sun protection since you could see the clouds thru the canopy. My wife didn't use sunscreen the entire week and got a light tan. So yes it provides sun protection.
This is lighter than my red sportbrella and easily fit 6-8 people comfortably. I also measured the distance between the poles when erected. I purchased the 10x9 model and the poles were 11ft apart on the long side and 8 1/2 ft on the short side. You can also install on grass using tent stakes or concrete using bricks,rocks or anything heavy.
My poles were sturdy so I don't know how people break them. Probably holding the bottom or middle when installing. Why carry a 40 pound large bulky pop up that needs at least 2 people to set up? Did not have any rain so I cannot comment on waterproof. I know it's not completely waterproof but how much will be revealed in future usage. Only downfall I have found. Some of my wife's purses are larger than the carrying bag for the Umardoo! I also prefer the bungee cord design vs the all Lycra new design.
I hope this review is helpful for people on the fence about purchasing one. A lot of people stopped by and asked about it, took pictures of the Umardoo logo to purchase from Amazon. You can spend a little or spend a lot for the same sun shelter. You decide. Would buy again definitely.

Took it to the Beach in Naples FL. When the sun was too much to bare sat under the shade cover.
It took less than 10 minutes to set up. Don't be shy on the amount of sand you use in the bags.

The initial delivery was less than spectacular. The item is lightweight, and packed up small. Upon opening the whole kit, we noticed a run in the material. It looked similar to a run in a stocking, hosiery. We were disappointed, as the run grew a little upon stretching the fabric. These shelters are highly effective due to the stretchy material. We felt a bit let down.

I contacted the seller via Amazon. I received an immediate response asking for my name, phone and address. They looked up my order, apologized and stated they would rectify the problem. They stated it would take a couple of weeks due to high volume of shipping.

Fast forward: we received a replacement unit. Same color and configuration of the original order. Thank you. Great customer service.

We used the damaged shelter in the meantime. Setup it's easy. We watched a couple of videos, and learned that if this is done properly, the shelter is solid on windy days. So solid that it outperforms our larger, hard leg, square shelters.

Set the fabric out on the ground, and extend the bags 45° from each corner, as far as they will allow. Fill with sand, dirt or rocks. Fill some more. No, really really fill them!! Lol. At this point extend the bags farther out, stretching the material a bit more. Assemble the poles, and place them in from the corners a little bit. We did best by putting them about 6-12" in from the corners, and equidistant from the sides. We use all four poles when the sun is overhead. We use two poles, and drop one side, when the sun is low.

Overall, we are very happy with this kit.

Lightweight
Small package
Looks great.. many compliments
great shelter
Sturdy in winds
Great customer service.

Highly recommended

Pretty easy to setup. Not super great with above average beach wind. It will pull the sandbags out of the ground. But overall pretty good for the price.
