I recently got the EALGRO 50 oz Tumbler and love it. The insulation is amazing—my coffee stays hot for hours, and my water stays icy cold all day long. I’ve even left ice in it overnight, and it was still there in the morning. The double-walled stainless steel feels super durable, and I love that it’s rust-free and doesn’t hold onto any weird smells.The large handle is so comfortable to hold, and it fits perfectly in my car’s cup holder. The 2-in-1 lid is genius—I use the straw for water and the flip-top for coffee, and both are completely spill-proof. Plus, it comes with extra straws and a cleaning brush, which is a nice touch. If you’re looking for a tumbler that’s stylish, functional, and keeps your drinks at the perfect temperature, this is it!
