KEITH TITANIUM Ti3150 Vacuum Insulated Tumbler - 10.8 fl oz ●●●●●●● Keith's 18th Anniversary: Exclusive Price!

This has replaced my 10oz Yeti Rambler. Note that, as other reviewers have noted, this is a smaller cup.I use it for my morning tea/coffee, my evening on-the-rocks, and sometimes for smaller amounts of water. Fit and finish of mine is very good.It's also quite a good nosing glass. I use it for this purpose when I travel.The lid is not a "press fit" type seal, but more of a cover. But it's still more useful than having no cover at all, especially if you're using it to keep more heat in or if you're using it as a nosing glass and want your dram to breathe in a covered environment.The net bag is great for travel, as it is very light and keeps the lid on the tumbler tight enough that it'll stay nearly silent in my bag.The tumbler is on the lighter side, but the base is has solid heft to it, so I don't have to worry about it tipping over.Unlike other double-walled titanium tumblers, this one's actually vacuum sealed. So it definitely keeps hot drinks hot and cold drinks cold.I'm a fan of the thin lip/edges, which feels more ergonomic to the lips than thicker steel tumblers.Finally, it looks great.

This tumbler is definitely an elegant and health friendly product. With complete titanium inside, it makes my drinking worry free of any potential harmful contamination from cup materials, and it very well preserves the genuine drink taste for much longer time compared to other types of cups. Complete outside titanium makes it very sturdy and durable. The vacuum insulation works great: with hot coffee or tea inside, I can hold the cup comfortably in my hand without feeling much heat at all. The titanium lid is very helpful too when I carry my coffee to my car or even for a stroll.One great discovery is that the coffee/tea leaf filter in product “Keith Titanium Ti3911 Ultralight Coffee Maker” can perfectly fit into this tumbler, so that I can make hot tea/coffee with this tumbler directly and conveniently.Love this product and recommend it strongly.

Was very well made but smaller than what I wanted

It's a nice little tumbler but it leaks alot of heat thru the single walled lid.

I decided to buy this mug after searching among many double wall titanium mugs. Love the design and the shape.The actual color looks much darker than the picture on amazon, but that's not a problem to me.The tumbler hold temperature very well, and the outside layer is only warm when I use with hot water.I love the global ID for each product, which is printed on the mug. It makes my tumbler unique.
