Quite a few reviews say that this thermos leaks. While the top can be a little fiddly to screw on correctly, if done correctly I’m certain that there is no way that this will leak. Just pay a little attention when you screw It on and you can’t go wrong. The top also has a feature that allows you to pour without removing the top completely. Ie you can loosen the top a three quarter turn or so and pour before retightening to seal. This is a great feature but I wonder whether some of those complaining about leaking have just failed to properly tighten the top. The flask is very attractive and keeps the heat reasonably well in my experience. However I usually only keep it for about 4 hours so I can’t say how hot the contents would be after a longer time. I have noticed that the top is not very well insulated, being made of plastic with a piece of polystyrene in the middle. So a small amount of heat definitely escapes there which higher end flask's probably don’t suffer from. Some reviews say that the flask lost its insulation after a while. This isn’t my experience. I’ve had this flask for 3 years and it still holds heat. However I have only been using the flask periodically over those 3 years. I suspect that like all “value” products their quality control isn’t the best, so you just have to expect that a certain number of duds will get through. It is just luck of the draw whether you are unlucky enough to get one. I’m certainly happy with the purchase and consider it good value.
