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

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.

The material in these sandbags is quite good. As others have pointed out, the weakness is the zippers. The inner zipper is particularly difficult to close. When a bag is filled, the two halves of the zipper are at too great an angle to close. If you force it, you will break it. With some effort, you can bring the two halves parallel and zip up. I found that if you close that zipper around an inch or so before filling the bags, it closes much more easily.I wouldn't trust these bags to hold sand. I used pea gravel from a local big box home improvement store. Not as heavy, but less chance of leakage. The 1/2 cubic foot bag filled three of the four sandbags. I opened the bag for a couple of weeks to let the gravel dry out and shook occasionally to help the dirt fall to the bottom. I inserted gallon size zip lock bags before filling the sandbags.

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.

These are double zippered similar to another set I bought. I added sand to them and would weigh them. The most I got in was 15lbs worth, not 20 and that's file. They'll secure a light stand well enough, but I was bothered by the fact that one of the zippers immediately went off track. So one pocket out of 8 has only one zipper holding in the sand. I was considering removing it, pitting a gallon zip shut baggie into it and having some extra protection that way. I haven't done that yet, but still may. I really don't want sand scattered all over my floor whena sandbag is dropped and the single zipper fails. I think with two zippers these are fine, with one I'm going to be careful with it. It's marked so I remember to handle with care.

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.

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!

La qualité est là

Its okay

Sind ok

These work really well for us once we managed to get them filled, dusted down etc.We are an events business so use weights all the time for many things. These are a good size and worked well for what we needed. We bought 12 of them and would buy more except for ONE thing. The zips.The inside zips in particular snag and are unusable on a few of teh bags. It is not a massive problem as we filled plastic bags into these sand bags and so the sand will not leak. But a better zip would be an improvement.Otehrwise they have been used to weigh down mike stands, lighting stands, backdrop stands, booth facades and more.These would be five star but for the zips. Fix the zips and we will a) buy more and b) push this up to a five star

These are perfect for placing along the bottom of my green screen to keep it extra tight and also at the bottom of the legs of my soft boxes (the bag that arrived with the soft box was absolutely useless and ripped within a day). These bags are very strong. I recommend putting heavy sand / ballast inside a plastic ziplock bag, stuffing inside the Fasmov fabric bag once you are at about 70%, and then finish the filling once in place. I give you full marks.
