Waited a month before I decide to write. This is a solid cup. Keeps a good heat for a couple hours. Was a bit dubious about the lid but so far no issues with leaks. It seems pretty bomb proof tho. Indeed just last night it survived me getting hit by a car at 30mph and me landing on it in my back pack. Pity I can't say the same for my back, landing on the cup seems to have caused some damage to me.
All in all. Would buy another.

Nice quality, great colours and a good size. They keep hot drinks warm for a decent amount of time and dont leak. Can't expect more than that

Nice size, keeps it hot for hours,easy to clean. Leak proof, Would recommend this one.

Great Mugs, I bought two and I am very pleased with them, seems leak proof so far and kept warm for a satisfactory time

Keeps drinks hot for hours and holds a large cup
Of tea or coffee.

Good quality, nice size. If you want great thermal insulation look at thermos flasks. Still good enough for short periods. Keeping it warm extended period as you drink it.

Really nice cup bigger than expected but love it.

It’s perfect if you need something leakproof. Fits a medium sized coffee from coffee shops. The lip of the lid does make it slightly difficult to drink and you have to be careful the part that opens it doesn’t accidentally come up, as it will then spill everywhere. V easy to clean and use.
