Long lasting for our dog. I'd buy again.
My wife fills the cups with applesauce, peanut butter and or pumpkin and then freezes it. The dog loves it and keeps him occupied for a little while. All his other toys and chews get chewed up in a couple of days and this has already been several weeks. I want to buy more cups if available. I'd buy it again and will look for similar items.
