We've used that litter before and our cats like it. Sammi will only go in clay litter, so we usually end up getting that kind of litter.
Also, the Litter Locker is a rip off. It's a great concept, but after we used our initial insert, we didn't feel inclined to spend $8 for a refill. Instead we use one of those 35lb. Tidy Cats pails that litter comes in. They seal tight and do the job just the same as the litter locker.
