Perfect for Windy Areas — Great Product and Support!
I live in Las Vegas, where the wind can be very strong. I’ve been trying many ways to hold up windbreak sheets to protect my plants, but nothing worked well — until I found this product. These water bags are sturdy and stable, and they work perfectly to keep the sheets in place. I had a small issue with one of the bags, and the seller resolved it quickly and kindly. Their customer service was outstanding, and I truly feel they are a very trustworthy company. Interestingly, I found this item through an AI recommendation, and I’m so glad I trusted it. I highly recommend this product and the seller!

Saved the day!
These have been a lifesaver! Right after purchading, I was a clinician at a horse festival and had a popup tent booth. We got hit with very severe storms. The wind was very intense, but these filled with water kept the canopy in place. Almost all of the others blew away. I have used them numerous times now. Super easy to fill with water and empty the water while packing to leave. I would absolutely buy them again.

Solid Weight Bags with Minor Strap Wear Over Time
After 2 years of outdoor use, these weight bags have held up extremely well. I use them to secure canopy legs, and they’ve never leaked. They’re easy to fill, and the built-in handles make them a breeze to move, even when full. The only downside is that the straps attaching to the canopy poles are starting to wear out—but that’s after years of use in the elements. Pros: ✅ No Leaks – Still watertight after heavy use ✅ Easy to Fill & Use – Simple setup ✅ Handles Make Moving Easy – Even when filled with water ✅ Sturdy Fabric – Withstands sun, wind, and rain Cons: ❌ Straps Wearing Out – Connection points showing wear after 2 years Final Thoughts: If you’re looking for reliable, easy-to-handle weight bags for canopies or shelters, these are a great investment. Just keep an eye on the straps over time. Still going strong after years outdoors!

Great quality
Great quality HOWEVER, it didn’t work for my canopy tent, the Velcro ties are not long enough to go around the legs of the tent. Will definitely work on your regular pop up tent, or a tent where the legs are not so thick. Great quality, excellent customer service.

Well designed with multiple points of attachment!
I was skeptical about these things due to numerous reviews of other brands that spoke of leaks right out of the box. However, this brand’s material is very thick and the seams are welded extremely well. They are also priced nicely for a set of four. I got the smaller ones (2 gallons each at just over 16lbs. when completely full). I keep them about 3/4 full to allow for heat expansion while sitting in direct sunlight. After a few months in the blazing hot southern Texas sun, I will provide an update. But since I only use two at a time and will have two in backup (they come 4 to a pack), I would not care if they only last a season or two. As you can see in my photos, they are puppy approved and are sufficient for keeping our shade secure, even during high winds. I highly recommend getting a set or two for whatever you need to anchor. And when you are ready to change out the water or store them, you can pour the water on your plants, etc.

Buyer Beware.
One bag had a hole in it and leaked half of the water in it in a couple of hours. When undoing the Velcro to move the location of the bag, one of the Velcro attachments ripped right off from the seams under very little tension. Would not recommend. Failed even before 1 use.

Excellent
I bought 4, then 2 more years ago. The 2 were a different manufacturer and failed in short order. So I bought these 4. Really great items. On many private grounds, the use of stakes is prohibited in RV sites. I use these instead for a screen house and two sun shades fir the ebikes and motorcycles. Work great. Even during storms with 35+ wind husts...never failed me. One holding each pole, and 4 guy lines using these instead of stakes. 8 total for screen house. Better than sand bags. Sand is great for the beach. But visiting mountains, plains, woods, etc. Where would you find sand? Do you want to haul multiple pounds of sand along? These you can fill up from tap, lake, river, or rain water.

Product as good as advertised
The bags were quick and easy to fill and held down a 10' X 10' canopy in 40 mph gusts no problem. Bages empty quick and easy after and push diwn flat getting the air out then all four easily go in the nice storage bag.

J'ai acheter un kit pour un chapiteau 10x10. Nous avons acheter 2 sac de sable de 30 kg. Ce qui donne environs 120lbs au total qui tiens le chapiteau. Je conseil un entonoir pour remplir le sable. Peux aussi être rempli d'eau. Nous l'avons tester et l'eau reste dedans comme si rien n'était. Tu peux vider l'eau à chaque utilisation.

No son del todo herméticas , al cabo de 3 dias , se sale el agua por la base . Les aconsejo que las llene de arena.

Pour le moment fait le job à voir sur le long terme, à l'air de qualité et plus facile d'utilisation que les sacs de sables et surtout moins fragile. Personnellement j ai coulé du béton a l interieur, pour un maintient optimal de mon barnum. Je pense être tranquille pour un moment.

Li ho comprati per tenere fermo il gazebo nei mercati. Ottimi perche salva spazio e vengono forniti di una custodia. Uno però perde acqua 🙄
