Review on 24 Oz IRON °FLASK Classic Tumbler - Vacuum Insulated Stainless Steel, Hot Cold, Double Walled Thermo Travel Mug, Water Metal Canteen by Sarah Mohamed

Bought to stop buying single use plastic mugs. The ice only lasted about an hour, and then my coffee got very watery. I didn't want to spend a lot of money so I went for a 24oz jar. The first day I got it I made a few cups of coffee in it and put it in the fridge overnight so I could add some ice the next morning. When I took it out of the fridge 10 hours later, THE COFFEE WAS STILL WARM! It's hard to fret over something that works so perfectly. I've been making iced coffee in it every morning for the past 2 weeks and I end my day with the same amount of ice I put in it in the morning. I love this mug and will probably buy many more so I never have to go without. **Edit** I've had this mug for a few months now. I'm bragging about it so much that all my 3 sisters, my mom, my best friend and a few co-workers all bought 1. I also "accidentally" opened a coffee shop where colleagues come to my house before work with their empty and clean iron coffee bottles filled with ice. I've only ever washed my glass and it still looks the same as the day I received it.
