Big nGreen issues us those, all the ones our crews have are filed with holes. The guys that use them keep the bottom ball under the cardboard or whatever at the bottom and it invariably seems to fall out and get all tangled. Even with my folding cube that happens, I run the bottom ball through the loop in the bag and then into a pocket and retain the top side with the velcro and a pocket but it still seems to get tangled. I guess its just a fact of life. I figured by having snaps to hold both sides I could at least eliminate knots in the line and limit the mess to bights and hitches.
Like anything if you take care of your tools they last and if you don't, they won't. The mesh cubes work, but for me, there are better options.
