Fasmov Heavy Duty Photographic Sandbag Studio Video Sand Bag for Light Stands, Boom Stand, Tripod,Pack of 4

I picked these up as dual-purpose sandbags--one use for weighting/dampening my tripod, and the other for weighting my light stand. The split-bag design works good for weighting around the light stand's feet, and the webbing strap makes it easy to put onto a tripod's center column hook. Further, the double zippers are on the "underside" and thus it's unlikely they can be opened accidentally.As for the bags themselves, I've only had the opportunity to use them twice, so I can't comment on the longevity. As mentioned, these are indeed empty bags--you need to add ballast yourself. 1st time I used miscellaneous stuff as ballast that was lying around the house. Since I was looking for a more permanent solution, prior to the second time, I bought a 50lb bag of playground sand at a local home improvement store, and filled the bags to 20lbs, 15lbs, 10lbs, and 5lbs respectively since I wanted options.For filling these, you'll want some other bag if you use granular ballast--like sand. The zippers aren't a hermetic seal. Your typical ziplock bag will work fine. Since the bags have 2 compartments you'll want to split the weight for each side. I was meticulous, using a scale to weigh out everything (i.e. for the 20lb bag fling up 2 ziplock bags with 10lbs of sand each), but I don't think you need to be as meticulous as I was.A ziplock bag, filled with 10lbs of sand (with the air evacuated as best as I could will just barely fit into a pocket--with a little maneuvering. Thus, it's safe to say that a bag will carry 20lbs of weight. The straps don't seem strained and the zippers with a bit of maneuvering will indeed close tight. Overall the weight was 20lbs and a couple of ounces for the heaviest one.Since I didn't want to overload my tripod for the 2nd time I used a bag (I had a large long lens attached to the tripod for the eclipse), I opted for the 5lb bag. Even 5lbs was able to dampen the tripod well enough in spite of the wind that accompanied the eclipse. I could have gone heavier for more dampening, but I didn't want to risk overloading the tripod.Overall, I'd say these are a great buy. Yeah, you need to do some of the prep work yourself, but I think this is minor. I'd highly recommend.

For the price, these do the job, look professional, and reduce the danger of injury and broken equipment. The double zipper makes them a little hard to fill, but it keeps leaking to a minimum. They can leak a tiny bit though. If I had it do do over, I'd put a ziploc inside each pocket and fill that with sand. I may yet, because I don't want to leave sand on a client's carpet. Filling is a pain because the double zippers make the hole small, but you do that once. Not a real problem. They hold enough sand for one to stabilize a softbox mounted directly on a stand. I haven't tried with a boom, but I suspect I'll want two bags for that job. I'm happy with these and am ordering another set.

Zippers are cheap but dont plan to be too rough on them and should be fine. If you are a bench shooter using them often this might not be the product for you. I will use them periodically and will work for me. Loved the price!

These are the first sandbags I've bought, so I've nothing to compare them to. I'm sure Hollywood doesn't use these but they seem to be solid. The material is heavy, the handles are sewn in well, there is a metal bar that runs across the top, in between the bags so that the sides don't sag. Following the advice I saw online, I filled 1-gallon ziplock bags about halfway and then stuffed the bags into the compartments to prevent leaks. I would imagine any sandbag would leak if you poured the sand directly into the compartment.It's also nice that one side is black and the other that high-visibility yellow stripe pattern. You can choose to "hide them" or make them plainly visible so nobody trips on them.I don't plan on throwing these bags around, so I expect they'll last a long time both material-wise and leak-wise. These are really nice sandbags and they low price is the icing on the cake. Recommended.

Sand bags.. Yes some of them can be cheap and fall apart but these are not those.I used pea stone this time vs sand and its much much better.The zippers can be a little bit of a pain but I think its because the material is stiff and they zippers are small. They all did work and I havent had any problems. Black sand bags. No frills

THE BADAs other reviewers have stated these "sand" bags have terrible zippers. Two were broken before I even unzipped them and they were impossible to close after opening them. I would never put actual sand in these bags. Your studio, trunk of your car, and anywhere else you take these bags will have more sand in it than the bags after one use.THE GOODThe material itself is very heavy duty. The handles are great, and I don't foresee any tears in their future. So how do you use sand bags that are useless for sand? Easy, use pebbles instead. I went to the local hardware store and got heavy duty ziplock bags and pebbles. I then double bagged the zip lock bags with the pebbles in them then put them in the sand bags. Works great, will never leak, and it's even waterproof so if I do a beach photo shoot only the sandbag will get wet, I will not have a heavy wet bag of pebbles.

Very well made, double zippers on each side! And the black and yellow stripes add a lot of visibility to the black metal stands. With two sides filled but not fully filled, the weight is enough to greatly increase the stability of the entire set up! Just trowled in some play sand into each side and zip up!

Very strong and well made bags. I filled mine with crushed granite after reading people warning about (a small bit of) sand coming out. We use these in our home with oak floors and carpets, so I don't want to worry about a trail of sand.They do a great job anchoring light stand legs when I cantilever a light out on a boom.The double zippers seem very strong and I had no problems with filling four bags.

Llegaron bien, tienen buen tamaño parecen resistentes pero vienen con doble zipper y el interior se safó al querer abrir lo más posible para introducir una bolsita desechable con la arena... el segundo cierre funciona bien pero probablemente con el uso y el peso no resista muchos años. Buena opción por el precio.

Nice studio bags that will keep what you place, safe, and what you place inside them, from leaking out.

La qualité est là

These are great sandbags. Large, well made, with decent zips. Very impressive for the money.

Works great and well made - ordered another set!
