Streeterville THERMALOCK™ Desk Mug, 420 ml

Stays hot for about 10-12 hours, ice cubes even longer! Pretty little cup, I've had no leakage issues with the lid. Get a good use out of one tea bag, makes a large mug size or 2 cup sizes, I like a pot of tea this one does just as well, I went for the greyish/white. It has a rubber bit at the bottom for non-slip. Don't forget you'll be drinking out of a tin can and it won't cool down like a cup it'll stay hot even after a few sips not your best china so has a different experience. Very pleased definitely recommend and buy again 5Stars

I've been using the Contigo Streeterville desk mug for a couple of weeks now, mostly at my desk and around the house. I pour my coffee in around 8 am, and it's still comfortably hot around noon so it easily holds heat for 4–5 hours. That matches what other reviews have reported about its vacuum insulation keeping drinks hot for hours and cold even longer. The stainless steel handle feels sturdy and makes sipping easier. The base has a rubberized grip that prevents sliding which is a nice touch. The lid isn’t completely leak proof and tilting it can cause a leak, but it’s splash proof at least but this should not be an issuse if used as a desk/office mug as intended. It is all dishwasher safe, so it's low maintenance. And the slider which slides over the sip hole can be removed for easy cleaning. I’ve had no staining issues yet, though I take care to rinse it fairly quickly after use. It holds a good amount, (420 ml), and fits nicely under my single-serve coffee maker which is perfect for refills. That said, it's too wide for a standard car cup holders, so it’s not great if you plan to commute with it. It’s a reliable desk mug. Keeps beverages at a good sipping temp for hours, feels solid, and is easy to clean. Not perfect for travel and can leak if tilted too much but for stationary use, especially at home or in the office (As designed for), it’s spot on.

Very pleased with the quality of this mug, great outdoors in winter for keeping your drinks hot. Some discolouration inside even after washing though.

Good 👍 keeps your drinks warm not leak proof but it isnt meant to be 😎

Excellent cup keeps hot for hours, perfect for lazy mornings in bed no need to refill as holds at least 2 mugs worth! Little bit of leak from the top but not worth dropping a star for. Does the job perfectly!

Nice mug holds 2 cups of tea coffee etc. Very difficult to drink from the opening in the lid its spills down my chin with every careful sip. Does not keep tea hot any longer than 3 hours then quickly cools. Sorry but I cannot recommend this desk mug.

Nice big mug. Keeps hot for ages. Does not leak.

Nice sturdy feeling mug, comfortable handle, really good sized, slightly bigger than an average mug, and the lid is pretty secure, haven’t done a leak test though!

Väldigt bra, håller värmen, skön att hålla!
