EMART Heavy Duty Sandbag Photo Studio Weight Bag Saddlebag Design for Photography Light Stand Tripod, Outdoor Patio, Sports, Pop up Tent, Umbrella Base, Camping, Fishing Chair -4 Packs Set(Black)

Not used yet so can't speak to durability but I am hopeful.BUT - one pouch of one saddlebag (2 pouches = 1 saddlebag) was received with a clean cut in the material of the pouch. Bummer. I have patched the cut material with a heavy duty tent repair patch using tent repair adhesive. I will be using the sand bags at the bottom of a stand that holds gun range targets. The weight of the bags keeps the target up in wind.Update: Seller saw the above review and reimbursed my payment without my ask. My patch is working well and the bags are very good for my task. Thank you seller. I changed the rating to 5*

The bags are empty and you have to fill it with sand. It comes with plastic zip lock which makes it easy to do. I bought a 50lb bag of play sand from Home Depot. That was enough and I was able to fill up all 8 bags with sand. The 2 zipper design was a great idea and feels more secure.

This sandbag kit comes with four double-sided sandbags. It also include several plastic lines which I have not used; I assume they are to put the sand in so that the bags themselves stay clean. I have chosen to put the sand directly into the bag pockets.East compartment is double-sealed. There are two full-length zippers that zip in opposite directions, so there is no concern of sand leaking out. The experience I had is that the zipper pulls are easy to get in position where they're difficult to close. I managed to get it each time though.Each compartment holds roughly 10 cups of sand, which is more than I thought it would.Each bag also comes with a clasp to attach it to what it's being used to hold down. I haven't found it necessary, but it's there.I'm using a couple of these on the base of my camera tripod. It's holding a PTZ camera nine feet up, so these sandbags help keep it steady so there is no vibration and it doesn't tip over if bumped.

I am using these on the legs of a metal canopy frame. These sandbags are made out of very sturdy fabric - much more sturdy than the more expensive ones I bought from a different company last year. The double zipper is handy and the included plastic bags are a good way to preload the sand without getting it all over the zippers. The only problem that I encountered, and decided to just live with, was that one of the inner zippers was not sewn correctly so that at the end the zipper foot just flew off rather than having a seam to stop at. Since I had already filled the other bags, and since the faulty bag was filled and zipped, I decided not to try to do a return or replacement. So out of the total 16 zippers only one failed. I still consider this good value for the money and recommend these sandbags to anyone needing to secure a stand or canopy.

Work will for my mic stands......good and strong and easy to fill with sand.

These bags are nice to add weight to my standing deck swing. It would slip all over when I would sit down or get out of the swing. I filled with sand and hung the bags over the bar swing.. Sure helps with the slipping!

The bags are ok and look great. The zipper is weak and one broke immediately after I added weight and tried zipping up. Now that I have added weight they should be ok. I figure the zippers will break if I open and close more than once.

The media could not be loaded. We use these sand bag on tripods all over the race track and they work great.!!! I have not had one leak thus far.
