ALEX Double Wall Vacuum Insulated Stainless Steel Travel Tumbler Cup With Bottle Opener On Bottom and Screw In Spill Proof Lid

very comfortable to hold, not slippery at all even with wet hands. leakproof if lid fully closed. Not as great at keeping things warm as it is at keeping them cold.

Great cup, it keeps the liquid warm or cold for a long time. I want another one for my husband

Love this cup. Works well just as described

Heavy-duty and lives up to its description about keeping beverages hot!

Good quality

This was a gift. She really liked it.

Love the locking cap. It's saved me and my computer from disaster. Keeps my coffee warm all day and the silicone sleeve feels great in hand.

This coffee mug if hefty and durable, it is a hard to gauge how much coffee is in the mug as the base is where the majority of the weight is. I cold brew to make keto coffee and use MCT oil daily, so have tried a lot of travel mugs and this one is the easiest to clean and truly leak proof. You can fill it up and shake it without spilling any liquid, and a little tip leave the cap open if you try filling it all the way up, if not the contents can spill out.
