900ml Heavy Sipper, Hot 6H and Cold 24H, Large Capacity Leak Proof Screw Lid Travel Mug, Double Wall Vacuum Insulated Coffee Travel Mug, BPA Free, Stainless Steel, Non Slip and Durable Coating, B201

Good quality, keeps drink hot and holds a generous amount of tea or coffee.May be too big for those with small hands and it's better used alongside a long spoon to stir your drink.Yet to use with cold drinks but I'll expect a equally good temperature control.

If you want a nice big mug this is for you, It’s just over double the size of a regular thermal mug and keeps your drink either hot or cold for hours. I’ve not had any issues with it but I would advise buying a handle or you might have an issue picking it up.

Let's get the bad thing out of the way first (I would have only knocked it down half a star if I could have) and I am not sure if this has happened to anyone else, but it seemed that the rubber gasket had some extra rubber on it and it would not seal to make it leakproof. It looked like the gasket had not been trimmed properly during manufacturing, which I would say means that not every one of these mugs or gaskets are checked for quality before being packed. It was easy enough to fix with a pair of scissors to trim off the excess, but not something me, as a customer should have to do.After the initial disappointment thinking I was going to have to send it back for a replacement, I have now been using it for a few days without issue. There is, however, a fine line between being leakproof and not, when tightening the lid, so I generally test it for leaks over the sink before use. I would also suggest that you don't over-tighten either, as some others have said it might be a little hard to get off again.I have seen that there are some comments around the weight of the product, so I have attached a couple of pictures. The first one is empty and the second one is 'full' of water (there will be variation in the full weight, as some people may fill it slightly fuller than other), which you could probably use as a weight to be able to train your biceps and shoulders with enough reps :-). The scales are in grams.I can't comment about the durability of it yet, as I have only been using it a few days.Anyway, I hope this helps someone in choosing this as their go-to mug on a daily basis.

Great product, large capacity but still fits into holder in car. Keeps liquid warm for hours

Leaked on first use as the seal was missing. Had to be returned

Bigger than I thought but a great product

Initially was ok but 9 months later I make my coffee in the morning for work I find I have to let the steam really settle down for at least 5 minutes before I screw the lid on because if I lift the cup with lid on it just pressurises out of the sides squirting everywhere (seems like rubbish seal) this is common every time now and is unusable unless you want just warm coffee because of how long you have to leave the lid off, and I don't fill it to the brim either. Also the lid is prone to jamming on. So no I wouldn't recommend it.

I love the size, the durability and design. However, it is absolutely not leak-proof - rendering this product completely useless. Dissapointed.
