Simple Modern 20oz. Classic Tumbler with Straw Lid & Flip Lid - Travel Mug Gift Vacuum Insulated Coffee Beer Pint Cup - 18/8 Stainless Steel Water Bottle -Seaside

I only owned this tumbler for about two weeks before the double wall started leaking. Now there is liquid trapped inside the cup where I can't clean it. I'm really grossed out by it. I followed the care instructions exactly. I expected so much more from Simple Modern. I'm so disappointed with this tumbler.

I love love love this bottle. The fact that you can use it as a hot cup or cold cup to save you money is a miracle! What's more, I've bought so many cups that claim to keep drinks hot/cold and this is the only cup that made true on their promise. I made coffee at 8am and when I got home at 9pm my coffee was still hot! The next day I tested it on keeping my drink cold and when I brought my cup with my drink still in it home and I opened it up my drink was still cold AND still had ice in it!! Money well spent and I will be buying a water bottle and a cup for my mom.

Keeps coffee hot/warm ALL day. Never leaks with the strawless lid. I've turned it upside down and shaken it many times, and it NEVER leaks. It's pretty. I give Simple Modern travel mugs as gifts now because I want my friends to have one, too.

SM makes the best cups! My coffee always stays hot for hours, or cold if it's iced! And they are so cute! I love that it came with the coffee lid and also a lid with a straw (and a spare)

First off, I'll say I ordered the bifrost color thinking, like others, that it was iridescent. Slightly disappointed that it's not, but not knocking off any stars. It's still a pretty cup. Beyond the aesthetics, this cup is awesome. I have a bunch of Starbucks tumblers and I'm never buying one of those again. Those get condensation and don't keep drinks cold for as long as I like. Simple Modern tumblers keep my drinks cold forever and don't sweat. Also, I can put my ice, water, and coffee concentrate in this thing, screw on the straw lid (without the straw in it), and shake it up and it doesn't leak. I'll definitely be buying more.
