Doesn’t maintain hot too long.
I love this cup because the material is good for heavy duty jobs like mine. I took off one star because it does keep hot but not for super long, it lasts hot for about 2-3 hours. Other than that it’s easy to wash and the magnet that comes on the cup is super strong which comes in handy for not loosing it. It magnetized on to the cup.

It's the best.
I'm picky on my coffee cups. Klien though has made a great cup for ones like me who work construction. This tumbler not only keeps your coffee hot, but is tough as hell. I can't count how many times it's fallen, dropped, or accidently kicked and still works like new. The rubber bottom and sides grip great. The magnet is strong and helps with tipping over, or possibly dropping. The locking lid also helps with spills.

Best tumbler I've ever owned
I use this tumbler as a travel cup for my coffee primarily. I have also drank cold beverages out of it. Both are satisfying experiences. Why does this product appeal to me so much that I would buy one, recieve it and then buy another? Because they got it RIGHT. They didn't waste time trying to put a handle on it that would be too big for some hands and too small for others. Instead, they put a grip surface on it that is comfortable and secure with or without gloves. A cup for all seasons and working men and women of America. The lid screws on, and the drink spout cover snaps in place open and closed. Even better, it doesn't rub on your nose when you drink out of it. Stainless steel inside and out, except for the thick lid and grip surface. Keeps coffee hot way longer than I'm used to, but don't know for sure how long because I don't waste much time drinking it. I have one for my truck and one for my Jeep so I'll never be without it. Yeah. Love it that much. I don't use the provided rare earth magnets for the cup, but I put them to good use elsewhere. I can see where they would come in handy in the construction or other trades. I use the cups on my commute, around the house, and while enjoying the outdoors. Keep up the good work, people!
