Bought my 1st set about a year ago & recently decided that I needed more…love the newer designs. I just wish they’d go on sale again so I could buy sets to share with/gift to friends & family. These are slim & tall, fit in my auto cup holders easily, and are a large enough size that I make my coffee in the morning before leaving for the office & still have warm coffee to sip on throughout mid-afternoon. The best part….they’re leak-proof!!! I desperately needed & LOVE this feature!! These lids don’t slide on; they’re not kept in place by suction & a rubber gripper ring…they screw on snuggly (as long as you pay attention & don’t cross-thread) -hard plastic lid to metal cup. They have a slide lever type of drink opening that audibly clicks/snaps. I make my coffee to go & literally toss it into my purse or work bag without worry. I’ve done this hundreds of times & never had a leak. Now I don’t need a hand dedicated just to carrying my coffee in/out of home/car/office. At the end of the day if there’s coffee leftover, I used to have to walk down to the break room to rinse out the cup then put a wad of paper towels inside -just in case a few drops of slightly brown liquid leaked into my purse/work bag/car interior or onto clothing. Now, empty or not- I just snap it closed & throw in the bag & go! If this review seems overly detailed or falsely exciting- then you just don’t get it. Maybe you’re not someone that needs this luxurious convenience in your life. For those of us trying to carry our whole day with us out the door, with maybe a kid on your hip as well- these are an amazing stress relieving gift.

My friends helped me purchase quite a few of these in store and online (I thought the online color pairs were better suited to my “giftees”) because they were supposed to be leak proof. Well, a couple of them were not leak proof. A few of them were difficult to open. And a few more had knicks on the inside of the lids. Some of the sliding locks on top were extremely loose. If you moved the cup from side to side, the slide would move and “jingle.” We should have tested them before we gifted them, and we should have looked at them closer. Maybe it is a quality control issue. If Sam’s Club will refund or exchange them, that would be great. Although we might have to look elsewhere for true leakproof tumblers. Disappointed.

Nice tumbler, I'm a little confused as to weather this can be put in dishwasher. Ello answer to the question is that it is top rack dishwasher safe but the instructions that come with the tumbler state that only the lid is top rack dishwasher safe. Confused

Excellent. Has a screw on lid. Keeps coffee hot.

Great product. Love the screw on lid.

Great travel drink container

These are great for busy people, I need a larger size , truly is spill proof.

Keeps coffee hot for hours

This cup is a solid leakproof travel mug.

Keeps my coffee hot for hours! Best one I ever had!
