Review on FELINEBOAT 17oz Stainless Steel Insulated Water Bottle - Keep Drinks Cold for 48 Hours and Hot for 24h with Triple-Layered Vacuum-Insulated Design - BPA-Free Container, Perfect for On-the-Go Use by Kevin Huot

This is a replacement for a water bottle that I carried with me everywhere until I lost it. This one has a matte finish on the outside to keep it in place; seals and keeps my water cold all day. I usually fill it almost to the brim and add a handful of ice cubes. The ice melts, but after a few hours the water stays cool and refreshing. The inside of the bottle is stainless steel, although the lid is plastic. It's 17 ounces (about a pint), which I think is the perfect size for easy portability. I even poured beer in it once and it was still fizzy the next day. Great insulated water bottle.
