I really love The Pioneer Woman's shows, magazine, and products, so I was excited to try this new water bottle. This is a very high-quality water bottle and insulating storage vessel. It is stainless steel, with what seems like an extra deep vacuum area, so the liquids stay at their original temperature for hours. The screw-on lid is also stainless steel -- and is hollow with it's own vacuum inside -- so it doesn't "leak" heat one way or the other. The strap on the bottle that connects to the lid is permanent, attached to both the lid and bottle, so it cannot be removed. For me, that's a really nice feature, because it means neither me or my children will ever lose the lid for it, which is the reason I have a half dozen lidless water bottles gathering dust in my kitchen cabinets. It takes a few twists to screw the lid on or off, but it's easy to do. The strap and seal seem to be made of super-high-quality silicon "rubber" which works great as a carrying strap, too. I really like the size, which is big but not too wide to carry easily. I also really love the color and the gorgeous floral design!
