MUCHENGHY 20oz Tumbler with Lid and Straw, Double Wall Stainless Steel Vacuum Insulated Tumblers, High Sealing Leak-proof Travel Coffee Mug for Hot and Cold Drinks(Silver, 12 Pack)

I was looking for a cup that I could stick in my bag and not worry if it fell over. This is perfect! No spills! The exterior is lovely and is holding up nicely. I hand wash, so not sure about the dishwasher. It holds temperature for hours. It is easy to clean. Just get one, it's lovely.

This is a great mug. It easily holds a 16 oz drink with ice. It does a great job of holding the temperature. It comes with a metal straw and cleaner, which I love. But the sealable drinking area is great too. It seals tightly whichever you use

I purchased a six pack of the tumblers. They're very nice and work great for hot and cold drinks. Lids are easy to install and remove with just a few turns. You need a metal or acrylic straw otherwise the strong spring operated stopper under the lid will crush anything else.One issue though. The bottom on one of the tumblers developed a crack. I use this tumbler daily. It was not dropped or bumped against anything even though it looks like a dent in the thin metal bottom. The depression is a result of the crack, which also deformed the bottom so it's now wobbly. My guess, since I drink hot coffee in it as well as cold water, is that hot and cold temperature changes caused the metal to expand and contract creating the crack.I'm hesitant to return them because the price was right, I like them, and the other five in the set are still fine for now. I got them to replace old plastic tumblers that sweat. I no longer need coasters.This set did not come with metal straws. I have a few already. While drinking water I pulled out the straw and the silicone insert came out with the straw. Not a big deal. It's nice to know they do come out for cleaning.I'm mildly irritated with the crack issue. Maybe I can fix it? But I'm overall satisfied with the tumblers.As of this writing, and within just a couple of weeks, the price has doubled, so I'll probably not purchase them again.

This is the best mug ever. Drinks stay hot for a long time. Once I placed my mug with a hot drink in the fridge and a few hours later, the exterior was cold but the drink was still warm. It's quite spill proof due to the spring where the straw goes. So if the mug topples, only a little liquid comes out from the straw. If the straw is not used, it's basically spill proof since the other drinking option is via an opening that is kept closed by a latch. Great value for the price!

The locking flip up cover to the drinking port and the entire design of these if awesome....They engrave with my laser very nicely and make great swag for our race team as well as gifts!TWO THUMBS UP -- VERY Highly Recommend BUY EM!!!!

Works amazing is my word for this cupIt keeps the coffee hot for a long time in a cold weatherJust, the sipping part to drink from is not so comfortable, but you can use the straw but since I don’t like drinking from a straw I have a issue with the sipping from the cover lidThx
