This is great for typical salting of the driveway and side walk. Works really well. Unfortunately, not ideal for salt spreaders. It's very fine and blows out of the spreader while driving down the road. We purchased a pallet thinking it was the same yellow bag stuff we purchased in 2012 but it wasn't.
This rock salt should be called powder salt because It looks like it is very old because it isn't in the traditional rock salt form. It also looks damp wich would give it more weight. It also wasn't the same name brand as in the picture.
