Review on AOZEX 64 oz Stainless Steel Water Bottle - Half Gallon, Double Wall Vacuum Insulated with 2 Leakproof Lids - Keep Drinks Cold for 24 Hrs/Hot for 12 Hrs! by Ben Walls

I had a need for many years. And I found it. I put it on my wish list for a long time, read the reviews of others - and finally decided on it. I don't like drinking out of stainless steel items but I'm VERY glad I got this. My "need" is that I sing and talk a lot, and when I'm active in this space I want hot/very warm CLEAR water to drink. It's been a challenge for a year. Not clean but hot water that is readily available. I boil a pot of water and put it in a thermos.2. I "tested" it - and I giggle every day because it works SO well. I "refreshed" my drinking cup after 3, 6, 9 hours. STILL very hot. After 12 now solid "warmth". I even had a cool 18 hours later. Totally sold for the quality of it. Already taken to the holiday exhibition - works great.
