Circular & Co Thermal Stainless Steel Travel Mug - 12oz/340ml - Insulated Reusable Coffee Cup - 100% Leakproof & Lockable - 6 Hours Hot/Cold - Push Top, One Hand Open, 360 Drinking Coffee Tumbler

This is a great cup and I'm very pleased I bought it (one of the reasons was because it's made of recycled materials). Not only is a good size but it actually keeps drinks hot for quite a long time. After 5 hours, my drink was still a good temperature to make it enjoyable to drink, and still drinkable after 6 (albeit not boiling hot). It's nice and slim to hold (good for hands that aren't massive) and looks very smart. It's easy to work the lock and there has been no leakage at all. I had previously bought the recycled plastic one but I didn't like it as drinks only stayed hot for about an hour. If you're wondering, definitely buy it.

I like most things about this cup, except it won't lock as described in the instructions and product listing. I've taken it to the gym with cold liquid (water) plus an ice cube added. At least two hours later the water was still very cold and the ice cube was not fully melted. This is certainly beneficial as I really don't like lukewarm water when I'm sweating after exercise. Separately, I went out for several hours and took tea in the cup and it kept warm very impressively. The cup holds a pint of liquid, which should be more than enough for most individuals for a few hours. As ever with something like this, the steam from hot liquid can build up and cause the lid to shoot off and liquid to spill all over you, so you need to be careful (there is a warning about this on the underside of the lid).I like the mechanism on the lid where you press down to open and close. It seems to be leak-free when closed. My only issue is that you're supposed to be able to twist the lid a little to lock it. The lid won't twist into the locked position no matter how hard I press down on it. Not a massive issue as I've never experienced a leak, but it would make me a bit wary if I had the cup inside a bag and was moving around a little. Otherwise, a very impressive cup that functions very well.

I hate sipping through a straw or a plastic protrusion and this cup lets you drink from anywhere once the lid is pressed. So easy. No leak and keeps things hot or cold. Perfect.

Keeps drink hot, still in one piece even after dropping several times.

My Citroen Cactus C4 has a very small slot for drinks - it'll fit a regular drinks can and is about 6cm wide so many travel cups won't fit. Despite the measurement listed on Amazon, this cup IS small enough to fit snugly in the space - meaning the width measurement given must be the widest point of the cup rather than the base. Cup sellers really must learn what a crucial part of choosing cups this is - showing all measurements is a game changer for people who want to take their cups in the car! (Incidentally - the 8oz plastic Circular and Co cup has a slightly wider taper and isn't such a close fit for my car.)I am genuinely delighted that I've been able to find a cup that goes in the dishwasher, keeps drinks properly warm and seals well enough to go in a bag - the long lifespan is a massive added bonus. This is the holy grail of travel cups - for many years I thought I'd never find such a thing.My coffee stays hot all the way to work and saves me having to reheat when I forget about it during the working day! I've since bought another cup for my husband.Excellent design - excellent eco credentials. Does ALL the things you want a travel cup to do... Finally!!!

The media could not be loaded. This is a very good quailty thermal travel mug, with is made from stainlesssteel, it had a capacity of16oz/454ml.It is very well insulated, on some occasions to insulated, but that's not really a problem.It had quite a different drinking design, you can drink from any part of the lid, rather than a traditional spout, or hole.It has a push click top to stop spillage.A little bit pricey at around £25 though.

We bought 2 of these to replace our R cups and they are a great upgrade. I lovw the 360 drinking mechanism but they keep the drinks hot for much longer than the non insulated version and also now have a lockable feature. Our r cups have lasted for 5+ years and only replacing as lost them (not broken) so I have high hopes that these will be fit for purpose for years to come.

Nice design, secure screw lid, keeps coffee hot fir a long time and doesn’t leak. Can’t ask more than that.
