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.

Before buying this I did a fair bit of research online, and bought some right rubbish as well. Beside generic junk, I had sampled Thermos' own Thermocafe range which felt plasticky and grim compared with their excellent flasks, of which I own several. Contigo also make very good quality travel cups and some of the negativity in reviews on this site looks to be generated by people imagining that this is a travel cup. It isn't. Others seem not to have read the instructions or the description. So here goes... This is a handsome looking desk mug. At 14oz. it is a good size. The "sake" shade that I chose is attractive. It has a rubber base that grips reasonably well and excellent insulation for a desk mug holding heat for several hours. With no screw down insulated lid, it cannot match a flask for heat retention or leakage but it is not intended to do so. Apparent "flaws" 1. It can spill/it leaks - because it is a desk mug (see above). This is explicit in both the description and the instructions - but the listing on this site is misleading with the phrase "leak proof". Is it a mistake? Just try not to knock it over, as you would with any mug. 2. The handle is uncomfortable and it is difficult to drink from - it is not uncomfortable for my large hands, in fact the opposite. I also have a big mouth (how can you tell?) so sipping from this is a pleasure. These "criticisms" reminds me of reviews complaining about hats being too big or small but with no reference to hat size, so, with that In mind, I take a large (not XL) mens glove and "One Size" hats rarely fit me. 3. The lid may pop off if the water is too hot - well yes. But this is because it is a press fit lid held in by its gasket. It specifically states that it may do this in the instructions and how to deal with it (I e., wait 3 minutes - in other words the time it takes to brew tea - who would have guessed?). 4. It is pricey - but it isn't when compared to desk mugs with heater and app at more than 10x the price, nor if, like me, you end up buying cheaper 'bargain' junk which needs replacing or binning. 5. It arrived dented/scratched/with coffee stains - that's horrible. So send it back! See Amazon's guarantee. A delivery problem does not merit a 1 or 2 star review for a quality product, especially if you can get a refund or replacement, photos or not. Because of the negative reviews on this very site, I very nearly passed on this one. I'm now thinking of getting a second, and maybe even one as a gift for a friend. Star ratings are all very well but read the reviews. I'm glad I did. I rarely give 5 star reviews myself, but honestly - this is worth it. I only hope it lasts - it does what it says it will do. Thank you Contigo. Edit - so happy was I that I ordered another for a Christmas present. A bit surprised that it arrived undamaged given that it had no box, just a plastic bag in an Amazon wrapper. Had to remove a star - as a warning to anyone giving this as a gift.

It stays hot for 3 hours, then warm for the next 2 hours. It is a very nice mug. The only issue that I have with it is that the colour outside wears out from use apart from ut it is a very nice mug and fancy

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!

I have two of these Grey and Blue and very shortly after buying them the paint peeled off????

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!

Very good Thermal cup, Very happy with this,
