Best tumbler available

Reduce mugs are the best. The handle is easy to hold and the tops stay on the top if accidentally dropped or knocked off a side table. Reduce has a huge selection avaiable and I love all the ones I have. These are stainless steel and last forever. I have purchased reduced tumblers (I call them mugs) since they have started selling these lovely mugs. I have 24, 40, and 50 oz mugs. Love all of these. Best customer service too. You can't go wrong purchasing anything from Reduce.

So far the best tumbler I own!

I just moved to southern Mississippi, and the old tumblers I had just couldn't keep up with the heat down here. I purchased this tumbler because i loved the beautiful seaglass color, fully not expecting it to stay cold all day, BUT IT DID!!! I left it in the car while taking my parent to an all day appointment in the hospital. When I came back to the car, it was 110°F in the car, the outside of my Cold1 was hot... but it was still full of ice on the inside! It blew me away that my drink was still ice cold, after 4 hours in the car in a parking lot. I love my Cold1 so much, I purchased a 2nd, and a 32oz Halo as well. When I make room for more, I'll be back!

My cup

So, I've had my cup for few years now, I didn't notice the bottom until today, but mine is old enough to where it doesn't have the logo on It... I love this cup and I highly recommend it for everyone
