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.

Durable, hard chew toy
My dog loves this toy!! He destroys everything but this has lasted us months. A lot of times he chews on it without us even filling the cup. Perfect size for a bigger dog like a golden retriever, but our small dog enjoys it too. Very durable chew toy!
