WACACO Octaroma Classico Vacuum Insulated Coffee Mug, Double-Wall Stainless Steel Travel Tumbler with Drinking Lid, 6 fl oz (180ml), Yellow

Amazing mug. The seal is top notch and has never leaked, yet it's easy to pop open and close (it can even be done with one hand while driving). It holds its temperature very, very well. Cannot fault this whatsoever.

Very good quality, ideal size, fits in your pocket.

Absolutely gorgeous little cups. One of the only brands to offer a 6oz insulated cup, that's also watertight. 8 and 10 are far too big for most coffee drinks. The finish and feel of the cup is excellent, and the colours are really not like the photos. I have the green and the yellow. They look so much better in real life vs the listing photos. They are a nice muted, matt colour. The paint is textured and the inside brushed stainless steel. A few people in coffee shops have commented on how good they look and asked where to get them. Now don't expect these to keep your drink hot like a flask would, these aren't flasks, these are insulated cups. Pre-heat the cup, put your drink in hot, and it'll be drinkable temp in 2-3 hours. As long as you close the lid properly, they are leak proof. I just chuck it in my backpack and go. There is a slight smell from the silicone on the lid, but it's gone after a few washes.

This will definitely keep your drink hot. Not for hours. Depends what you want it for. It’s good for taking on the go. It feels nice, the design is good. I’ve had no issues with it. Have used it for a few months and still enjoying it. The seal is good. But, I keep it upright and secure because I’m not brave enough to let it roll around in my bag. So I can’t comment on the leak proof qualities

Sooo amazing. Easy to hold, very easy to clean. No problem so far ie leak and it’s clearly leakproof. 6oz size is 10/10

Just the right size for cup holders in a car and van I use it for work keeps the drinks hot for ages.

Very cool design, doesn’t leak (so far), looks small but is actually a full standard cup and keeps the heat really well. However the leak seal rubber has been poorly designed so the air hole which is designed to break the vacuum as you drink is always covered by the seal. To drink on the go, you either have to try and fully peel back or removed the rubber too or remove the lid fully. Functionality is poor because of this, otherwise would have been 5*. If the rubber seal that rotates 360 degrees was A symmetric, than there would be a way to actually drink on the go.

This is a great take out cup no leaks just the right size for a coffee brilliant
