I've been putting off sandbags for years, but having switched to C-Stands, they become a must have. I ordered some "fill them yourself" bags from the jungle store, but was not impressed, and decided to just order some. After some research, found The Sandbag Store and their saddle bags. I went with orange because I wanted them very visible since I work with people with disabilities, including visually impaired people. The bags are top quality, the stitching is well done and will not be coming out! I anticipate many, many years of service out of them.
I got 6, will probably order 4 more down the road.
