Stainless Steel Insulated Tumbler 30oz, Double Wall Vacuum Insulated Travel Tumbler 18/8 Stainless Steel with Lid

it did not arrive with a spill-proof lid that allows me to shake my drink before i take a swig - one that wont leak at the slightest lean in the car or while carrying it. today's drinks are rarely pure water - they're often colored powders that need a shake before each swig. surprised this aspect ignored. that said, it keeps drinks cool for 3-4hrs in a 90F car. i'm guessing the opening in the lid doesnt help. the lid needs an upgrade.

My primary reason for choosing this tumbler is that it's advertised as all parts 100% dishwasher safe. I will use it for a year, wash it in the dishwasher and see if it's truly dishwasher safe as advertised. I like it so far, thus the 4 star rating. If it's held up after a year has passed, I will change this to a 5 star rating. If it fails before the year has passed, I will adjust my review and rating downward sooner. Crossing my fingers!

Love these cups! If you've never tried a double walled stainless steel cup, you really don't know what you've been missing. These will keep ice for over 24 hours and never sweat. My only gripe is that the lid is made out of plastic (could be HARDER plastic). When I dropped my cup last week it hit the floor lid first and broke in four pieces. I have yet to find just a replacement lid.

Really like this. I should have got the 20oz instead. This 30oz does fit in cup holder of car, but is big for my normal'ish hands. Plus could have bought two for the price of one "name brand"

The cup works well to keep beverages warm but my lid cracked the first day when I took it off to refill my cup.

Bigger than I thought it would be but it's pretty great. Holds a lot of cold coffee and basically fits in the cup holders in my car.

I have now ordered a second one of these tumblers. They are just as good if not better then the more expensive ones.

Works as good as Yeti, for a lot less money. It keeps ice over 12 hours.
