Review on The Ultimate Insul8 Beer Bottle Cooler: 12 oz. Double Wall Insulated Stainless Steel Holder for Long-Neck and Standard Bottles - Includes Bonus Bottle Opener Keyring and Stylish Gift Box by Pedro Hague

If you want to put the bottle in the cooler, you must first remove the cap from the bottle, otherwise the seal will break. It keeps the cold of the bottle quite well and protects your hand from wet and cold. Seems to be working fine so far. Don't like to take off the bottle cap before putting it in the cooler, and you need to push the bottle all the way in before putting the bottom on, otherwise the bottom cap will become cross thread. Most bottle caps are screw type, so you don't need a puller, but I think I'll find a use for it.
