Haven't used them alot but seem good. Zipper is fine sticking okay fabric is decent. They are a little less quality than more expensive ones but like one Zipper and fabric maybe little thinner. But for price comparison worth it

I bought these to hold my pool cover down. The size is just as described. They come with Ziploc bags that fit inside the black bag. Although I did not need the ziploc bag because I put pea gravel in the black bag compartments. The bags are sturdy large enough to do the job and I think they would work very well to hold just about anything down. I especially like the fact that they come with the clips that you can attach to the handles of the bag to fix them in place, I attached them to the grommets of the pool cover and the bags are sitting on the ground ( I have an extra large pool cover on purpose) so this is just perfect it puts enough weight and tension on the pool cover without actually over stressing the grommets. In fact I'm so happy with them I've ordered another set.

This was the second bag I was filling, turned it over and found that the handle had detached. Hadn't put it under stress of weigh, just came this way.I will have to inspect the other ten to see if the same issue will crop up.Have been using now for a couple of days, bags are loaded with 14lbs of sand (7lbs each side), and the hand grips are failing every time I pick one up!

Inside plastic bags are cheap.

I love these! They are durable! They come with easy to fill zip lock backs to insert into the zippered pockets on either side. I was surprised by the quality of the thick material. These will last a long time. The price is very good as well.

They do the job of holding down my balcony chairs. My condo is on the 15th floor and we get lots of heavy wind. I filled them with garden rocks and attached them to the chair bottoms. Now I don’t sweat the storm winds

Easy to fill and use.

My first common is that the zippers tend to open themselves up when you carry the bags by the handles and this would let the sand fall out,. We found we had to tape them so they would not move.Some of them the sewing quality is questionable. They do not double stitch so we’ve had a couple open up from the bottom. For the price they are OK.
