Great drink tumbler

I love the reduce mug and tumbler products. I have been using the 50 oz tumblers daily for two plus years and the 50 oz mug for a year plus before that for my water. These keep me hydrated and fit perfect in my car. I have also given them as gifts. I bought this to replace my yeti. It is the perfect size for lots of ice and my 16 oz Mountain Dew. I also have the stainless steel lids to insulate even better. I like cold drinks.

I'm satisfied with this purchase. I know that people rave about the Stanley Cup, but I think they are over priced and overrated. This is no way to downplay Stanley at all but I feel the materials used for all these cups are the same. Save yourselves some money and grab one of these. Now I will say that the hours of keeping your drink cold or hot are not as good as some but you have to figure the top/lid is clear plastic and it's not a metal screw on top like some, but it works. At least for me 😊

Beautiful color, thick and sturdy handle, PUSH DOWN lid (instead of screw on), AND a silicone bumper ring around the bottom so the cup isn't loud to set down, this tumbler has it all! Needed a giant tumbler for postpartum and this one has been perfect. Helps me get my water in, stays cold all night long, and isn't loud to set down so I'm not worried about waking the sleeping baby. Reduce has been recommended to me so many times and I'm so glad that I decided to go with their tumbler when I needed one!
