TOMIC 20 oz Double Wall Vacuum Insulated Stainless Steel Tumbler with Clear Lid. Keep Drinks Hot and Cold. Resistant to stains and odors, sweat & BPA Free (Brushed Stainless)

Purchased this because it would fit in my car cup holder. It is a 20 oz mug, so not huge. I don't use for hot drinks, mostly iced water. It does a pretty good job keeping the water cold for a few hours in a hot car. I hand wash them (I purchased 2). The lids are easy to remove, pull off. I never hesitate to update my reviews should new info seem useful.

I bought one of the black ones months ago for myself, after searching for a travel mug that would actually keep my coffee hot for longer than a half hour. I can attest to the fact, this tumbler does keep my coffee hot for a good hour plus, and a good temp even longer than a few hours. I had to buy one of the silver tumblers for my husband, because he kept "borrowing" mine! We are both very pleased with our travel tumblers.

1）Great qualitityThe thermos is perfect size. I looked for the smaller one. It’s super light weight and the build quality is wonderful. Lid has a rubber texture was is nice and grippy. The fit and finish is top notch too. Love it.2）Truly keeps things cold for over 24 hoursI am very picky about water bottles and I have to say that this one exceeded my expectations. It keeps liquid cold for over 24 hours and will be perfect 。 I loved the textured finish . Excellent product!

Finally a mug that keeps liquids hot or cold for a good amount of time!

I bought this mainly for coffee, but will definitely use it for cold drinks as well. My hands are small and I was concerned about the size. I have no problem picking it up or holding it. Very pleased with purchase.

Working in a shop I don’t always get to finish my coffee before it got cold. This cup keeps it hot for over an hour it’s nice on those long morning rides too.

AMAZING I ordered one for my boyfriend and another for myself. :) It truly keeps your beverage cold. Ice melts very slow good for hot days.

I read a review that this tumbler kept drinks hot for hours. Not in my experience. More like 45 minutes. So, more useless dust collectors in my cabinet.
