12 Packs Photography Weight Bags Photo Studio Filled Weight Bag Empty Heavy Sandbag Set for Photography Tripod Stand Light Stand Sports Outdoor Photo Video Studio Boom Brackets (Black)

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.

The fabric used in this set is top of the line, i have no fear of them being torn with weight inside the bags. My only negative is that the internal bags are difficult to fill because they’re “normal” ziplock bags that have no base to hold it up

Basics, they just work. Price is more or less like the others. Quality is not bad.

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

I found that these kind of sucked. The nylon webbing that handles are made out of kept separating from the bag itself when you tried to use it as its intended purpose: A HANDLE! Poor quality indeed, with a few of them ripping on the first usage. I needed them for a project the next day and didn't have time to return so I stayed up late sewing the handles on with a better thread. You can't really overfill these, so I know I didn't use too much weight. These black bags are kind of crappy and I wouldn't recommend buying them unless you're not planning on ever using the handle to move them around.

Great for backdrops and diferentes structures.

I filled it with rocks and use it to weight down my arches. They work great so far.
