Review on Vargo T 406 Titanium Travel Mug by Ethan Carpenter

I bought this mug to save space by placing it on the bottom of a 32 ounce Nalgene bottle. Unfortunately, since the product description doesn't state a size, I read the reviews and decided it would fit. It's not like this. While I can't use it for its intended purpose, it still fits around a thinner water bottle and I'm sure it will find its place in one of my backpacks. I gave it 4 stars because it's still a good mug, light and strong, if a bit pricey. The product description should be more detailed.
