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!

Good cup
Great cup, love the long lasting seal. the magnet fob is strong enough to hold a full cup which is great. Holding warmth...id say 6/10 Keeps warm of its full for about 3 hrs give or take but half full it tanks pretty fast.

Sturdy good grip
Bought this because it had good reviews and looked sturdy... with the previous, other name tumblers, if you dropped the lids they broke and the company dont have replacement lids so you had to buy the whole thing! Gets expensive... no issues with this tumbler.. my husband really likes it, fits our cup holders and has a good grip..
