WARNING, IT DOES SPILL!Been using this for quite some time now, and it definitely keeps my drink hot - like as if it had just come out of the kettle even after many hours. I could keep the lid closed and enjoy it at the end of a class.However, IT DOES SPILL. I tested it by turning it upside down, and from side to side, and it spilled quite a lot (not so much on its side) so I would recommend keeping it upright or buying a small thermostat instead if this is a worry for you. I did put this in my bag once, upright, since I have had problems in the past with cups like this. A little bit of my drink had spilled, not bad enough to damage anything. Probably not a good idea to have your cup on the side.Love the look of it, and I quite like the grip since it helps keep a good hold.It’s relatively light and sturdy. Doesn't feel heavy at all.

The cup you drink your coffee from is very important and this is a fair cup for the price. Not my favourite and probably wouldn’t buy again but it does the job it’s intended too and is comfortable to use and the hand grip is great too. I’ve been using it for a good period of time and the grip is still held on good and tight.

Super pleased with my travel mugs. Keep drinks hot for hours or cold. Even the ice cubes in cold drinks stay cold and clinky. Best to pre warm for hot drinks. Easy to clean. Nice to drink out of.

Insulated travel coffee mug. The top unscrews and the cup takes about a mugs worth of whatever you choose to put in it. If properly secured, the cup will keep contents hot or chilled for a good couple of hours. The lid flaps back to reveal a hole for drinking through. When this is pushed tightly shut, it creats a waterproof seal. I have tried holding the mug upside down, and do not get any leakage, As a buonus, the cup will also fit in a large coat pocket. Comes in a range of colours which is nice.

water tight. good lid closer. decent size and keeps drinks hot/cold for extended periods of time. stylish and good price.

This cup keeps your drink hot for hours. It has a great lid to prevent spills. The lid is so tight I'm not worried about it coming loose as well.

I ordered 2 at the same time, one came wrapped in plastic inside a box, the other was just loose inside a box. The loose one leaks, I suspect it had already previously been returned and resold, hence the missing plastic. Reading the other comments and as per my experience, these seem hit-and-miss as to whether they leak or not.Note: I am capable of screwing on a lid without cross threading etc, and even tried by only half filling the cup. It just leaks no matter what. Hot and cold liquid.
