This is great for removing ice %26 snow. I put it on the driveway before snow or turning to ice. It melts it almost immediately

well, waited through 2 snow storms to get this. finally its here, but hey, its spilling out the bottom. i flip the box over to see this. the box wasnt even intact. All 4 conrainers... busted. waste of $80

Either this is a great deal or a complete rip-off. The header says 40 lb and it's a 4 ct. You might be thinking you are getting a total of 160 lb. but if you look carefully at the label each container is 9.5 lb and it's been rounded up to 10 lbs., which means that instead of 160 lb you're going to receive 40 lb total (4X10 lb). In my case the product was damaged in shipment and returned to sender. After 2 weeks of not hearing from the vendor (yes, it's sold and shipped by a third party vendor) Sam's agreed to refund the charge. Before purchasing, it is suggested you find out if you are buying four ten pound containers for a total of 40 lbs or if you are purchasing four cases with each case containing four ten pound containers for a total of 160 lbs.
