Review on 🧊 Kälvin Insulated Water Bottle, 7.6 oz (225ml) - Shake-to-Activate Hand Warmer and Ice Pack, BPA-Free, Hot Water Bottle [Silver] by John Surabhi

I was looking for something to store tea and keep it warm during my long daily commute. This article is the best! It not only keeps the temperature of the tea for several hours, but also serves as a hand warmer. Shake this thing up with a warm drink in it and it will instantly release the heat from the bottle. I use it every morning to keep my hands warm while waiting for my car to warm up. It has a large opening that allows me to pour tea easily and has a comfortable rubber grip at the top as shown in my first photo. I showed it to my niece who plays sports and she asked me for one for lacrosse season after trying the cooling function. We've been buying water bottles from Sigg (a Swiss company) for years, they're about the same price but much nicer. My only wish is that they sell replacement caps, but that wouldn't stop me from buying again.
