TEKKER’S Insulated Coffee Mug Stainless Steel Tumbler 14 oz On The Go Coffee Travel Mug Vacuum Cup Tea Flask Black

I was looking for a rambler and was about to purchase another one when an ad for this one caught my eye. I had never heard of the brand, and looked it up. I really couldn’t find anything on it at all. It was cheap enough and I really liked the design/overall look of it that I just bought it.I have seen a few people mention that it may not be the best for using while driving, but I have had no issues on that front. If you look passed the cap and don’t focus on it, your eyes will adjust and you’ll have little to no interference with vision. It doesn’t leak, and keeps coffee/tea warm for a good amount of time. Which is almost a detriment for me as I don’t like my coffee scalding hot, but that’s my own issue. Very solid product all in all. The cream and brown look is great.

I have been using it for a couple of weeks now and really love this mug. I have not tested it out with cold drinks, but it keeps my tea hot for hours on end. It almost keeps it too hot and I often need to take the lid off to cool my drink down a little. I like the design of the lock for the flip up lid. It makes taking a sip one handed very easy. It feels solidly built and looks like it will last for a long time.

This is my new favorite go-to coffee cup! It's the perfect size for my Keurig Mini and fits in my laptop backpack's side cup holder. It's leak-proof, cute, and the locking mechanism works as intended. The top is pop off so some might not like it, but it's something I myself appreciate. It's also super easy to clean (unlike my previous Zojirushi bottle). It's not too heavy like a Hydroflask, but is durable enough to survive me. My coffee stays hot and I am one happy camper. :)Edit: I've had to lower my review rating because after a few months of use, the locking mechanism has failed to function properly. This was one of my favorite features and since that's no longer working, I find myself hardly using this cup nowadays. I've upgraded to the new Takeya 17 oz Travel Mug which also features locking function, a fold down handle and still fits under my Keurig Mini.

I spent so long looking for a cup that will keep my tea warm for a long time and this does the job. I was happy with the price too

I'm sure they aren't always like this, but mine leaks. Not very happy with it. It holds temperatures pretty well and for a good amount of time. A sealed tumbler that leaks is useless.

I made my coffee at 11pm, on my way to work at 7am it was hot! Like HOT) no spill and i don't understand why some reviews mentioned previously that it is uncomfortable to drink? i was skeptical because of that but i don't regret at all buying it!No more plastic waste:)

The mug look great, keeps my coffee hot. It is a nice diameter, my hand fits nicely around it for a good grip. But the design of the top doesn't do well when taking a drink. When you take a drink, my nose hits the flip top of the mug. Other than the placement of the flip top, I love the mug. I live in northern MN and am out in negative degrees outdoors, this is my go to mug for coffee, as it stays hot.

This mug could be perfect but for lid problems. I bought one mugs 12/2020. On one the lid slips into a lock position. I could live with that (although it's annoying). The 2nd mug's lid broke after 7 months. It no longer pops open & falls on your nose while drinking. However, they do keep beverages cold or hot as advertised. Would give 5 stars but for the lid issues.

Everything looks good and all of the features are better than I expected
