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

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

These work Great but we're a bit of a pain to load with sand and zip up. If you fill them too much they can seem to be even harder to close. Not the finest time. But I've ready they query Great and are sturdy

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.

2 of the zippers broke when trying to close them 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.

These bags are heavy enough to withstand regular use; inside and outside zippers work well. Filled them with pea gravel, so no issue with sand leakage. They work well and are reasonably priced. Very satisfactory.

They are poorly made and do not last. Clients are not happy when they break on set. And they will!
