Ozark Trail 22 oz Vacuum Insulated Stainless Steel Tumbler, White

I've had this travel mug for a week and I can honestly say it's the best one I've ever purchased. I live in the heart of the “Heat Dome” south. Heat index well above 100 degrees and this keeps my drink ice cold for hours! Keeps drinks hot just as well. The lid seals super tight. But the very best feature is the magnetic slider. It simply is attached with a pair of magnets. Easy to slide. Incredibly easy to remove. I can't tell you how many mugs I've thrown away because the slider broke either on its on or by me trying to remove it or put it back while cleaning it. Not a problem with this one. It's as simple as separating magnets. This is definitely a mug worthy of 5 stars.
