For a product that costs around €30, it is very small in volume, easy to set up and take down, and provides shade over a large area, it is definitely worth it. I imagine everyone's concern is how it performs in windy conditions.

Today, according to Windy, we had wind speeds of 3 to 4 Beaufort, so staying on the beach was not entirely comfortable. The other classic umbrellas were shaking quite a bit. With this specific tent, I tried various things, removed two rods to give it an angle, removed four rods to lower it, changed the position of the pegs, basically tried everything. Eventually, at some point, I managed to stabilize it enough and it was in the condition you see in the photos, I remind you that we are talking about 3-4 Beaufort winds. After a few more attempts, I put back the four sections of the uprights that I had initially removed and the tent remained satisfactorily stable even in this wind.

It goes without saying that it endured and did not tear, as its sensitive points are reinforced. Inside, there are 8 thin, small iron pegs and enough rope to stabilize it around, which are insufficient in strong winds or if the sand is excessively loose. The supply of 12 uprights is a must.

A much better solution than traditional umbrellas, just don't go and set it up in the middle of the crowd and dominate the entire surrounding area, go somewhere remote so as not to disturb others.

UPDATE:
After 4 setups, I can say that it does indeed withstand the wind. And you don't need 12 uprights, even 4 are enough, but with 8 uprights, you achieve excellent results in moderate to strong winds and on any soft ground, with the only negatives being the noise from the flapping fabric. And if someone is a perfectionist, they can achieve really good setup, which creates a bit of noise.

I haven't noticed any signs of wear and tear yet, but at this price point, it pays off from the second use compared to visiting a beach bar.

The product, as sold, without any additional equipment, is simply useless. It cannot withstand even the slightest breeze. The legs do not anchor in the sand or on a rock, they do not have such construction.

The situation is somewhat salvageable, and you will need: 4 bases to place the 4 legs. Enough rope to tie the 4 corners, each one to at least a 10kg rock, to keep it stable. And string/rope to tie each edge of the fabric to the top of the base, so that the edge does not come out of the hole in the top.

Even in this scenario, where you spend about a quarter of the price and with the help of a second person, and it eventually stands decently, I did not test it in many windy conditions, and it seems quite risky, as the tent does not have any provision to release the air. In other words, I'm afraid that with more than 3-4 strong winds, it will "take us and lift us".

It goes without saying that there is no guide or source on the internet, and no matter which store I asked where they were selling it for more information before buying it, no one had the slightest idea.

The tent, if set up correctly, provides adequate shade for 4 people with towels, but it will be more cramped for 4 sunbeds.

The 4 legs seem poorly constructed, I doubt they will withstand more than 5-10 tent setups before falling apart. I consider the overall cost to be exorbitant, as with the 30 euros I spent (I wanted to buy it immediately from a physical store, my goodness), I can buy 3 square meters of nylon and 4 sturdy legs. The packaging is very small and convenient, a long narrow bag.

At least now the rest of you know, only buy if you are willing to do the above, and still with risky results for more than 3 strong winds. Otherwise, an umbrella with all its pros and cons..

Edit: The 3 square meters of nylon with the 4 iron legs are in the trash. Tragic even with 1 strong wind. It almost ruined my vacation. Make sure it doesn't ruin yours. Spend a little more, even double or triple, so that you don't become the laughingstock of the beach, nor envy the real shade structures you see around you.
