SmoothSip Slider Insulated Stainless Steel Coffee Tumbler, Reusable Iced Coffee Cup, Hot Coffee Travel Mug, BPA Free 20 oz, Sour Apple

Somehow keeps the coffee scorching hot for hours and hours. Have to have the lid off until it's drinking temp and then it keeps it there until I finish the coffee, which can take me a while some days. So glad I bought it!

Great cup, keeps my drink cold for over 12 hours. The color is not as vibrant as the picture but still very lovely.

Love how this cup works, keeps drinks cold for hours on end. Perfect for someone who works a desk job.

Its a great choice if u need a good quality budget liquid tight drink cup. Although....don't use certain liquids and leave it in a sink or anything like this or forget to rinse it. The seal mechanism is impossible to take apart without breaking it. If you do...soak the lid in hot ass soapy water (dawn grease cutter) for an hr then wash with scrub brush rinse and repeat until clean. Other then that its great!!! I use it around my pc so if it falls over even while open its a slow drain. But while closed....doesn't drip at all even with coke pressure on it. I left it upside down after filling it with root beer 3/4 full shook the hell out of it turned it upside down over night no leaks and was still cold amd carbonated. Next nite I did the same with it upright....same results. Be careful when you slide it open liquid may rush out depending on internal pressure.

Is not fully leak proof. It’s leak proof on the drinking spout but if you tilt the cup liquid will spill out of the sliding valve on top.
