The bowl itself is fantastic, just the right size. It rolls up nicely in to a very compact form, but is big and sturdy enough to hold plenty of food of water for our 65 lb dog. The bowl definitely feels like high quality material and love the look! My only feedback is on the bungee strap. We hook this to our leash to ensure we always have a bowl with us, but the strap is either too loose and the bowl pops open or you have to double loop it and it is very tight. Would be great to have something that is adjustable. It would also be great to have a small tab/loop to hook it on to a leash, backpack, etc.

It's easy to find portable dog water bowls, but none with the quality you'll find from the Stunt Puppy Nano Bowl.
The Nano Bowl is tough in a tiny package and it weighs next to nothing. It's difficult for me to carry a ton while walking my dog. It's very helpful that the Nano Bowl can attach to my Stunt Runner leash. I attach it in a different way than what is shown on the product page. I wrap the bungee cord around the waist part of my Stunt Runner and pull the bowl through. It's because I don't want to unclip my dog from myself for safety reasons.
The wideness of the bowl mouth is great for my wide-faced dog. He didn't have any trouble lapping up water when we took a break from our outing. The neutral grey color is great that it matches with a variety of other colors.
