Esbit VF750ML Vacuum Flask, Stainless Steel, Black

We brought one of these but the smaller ones several years ago and it was brilliant. We needed a bigger one so ordered this one. It arrived well packaged and very quick. The only problem was both of the tops leaked. Not just a drip or two but a constant flow. Arranged for a replacement which arrived within three days. The new one is perfect with no leak at all. We have come to the conclusion that the first one had the wrong tops as there was no damage to the actual thread but it didn't seal which caused the leak. The replacement fits much better which is why it doesn't leak at all. These flasks are brilliant and keep the drink hot all day. Can highly recommend.

Just received this 750ml flask, pre-heated it for a few mins with boiling water then filled again with boiling water. 12 hours later tried it and the water was still piping hot - way hotter than previous flasks I have owned. Tried both caps - no leaks and push-button cap worked perfectly. Nicely made and well finished flask.Exactly as hoped for - just the job, well chuffed.

Really good, well made flask, wide enough to not scald yourself when filling. Drinks are always hot even after 5 or 6 hours, and I always warm the flask first before filling, this helps a lot. It comes with 2 stoppers, a Screw Cap and a Push Stopper. I always use the Screw Cap, much better seal and more hygienic. Has a Large cup and a smaller cup inside. Have used it lots of times now when out walking.

Filled with hot water night before to warm flask through. Made coffee 7am following morning, was still beautifully hot 6pm. Love the choice of stopper, personally prefer the screw top, others may prefer the pop-up, but great that you get the choice. Only small criticism is that the cup does get very warm while drinking, but on the other hand, keeps your drink hot!

Extremely well thought out and manufactured product, very classy for a simple task of keeping your liquids hot or cold. I like the capacity of 750ml, enough for two without the extra weight a full litre brings. Two cups and a choice of two different stopppers make this a very flexible flask. Really nicely made and does the job superbly.

This flask definitely keeps water hot for 24 hrs (measured at 60 degrees). I have left it in the car overnight in winter and it is still warm at middle of next day. It has a good sized drinking cup (250ml) with a smaller second cup inside. The two lids both seal fine - nevertheless this gives you two rubber seals in case one fails. 750ml is the right volume for a person for a full day out (equal to 2 drinks cans), without being too heavy. Having tested several flasks to replace my 30-year-old one, this was by far the best, so I've now purchased a second one for the overnight trips.

Brought this for the other half, who needs a flask for his morning cuppa at work. Really impressed with it, have purchased cheaper ones in the past but this seems really sturdy and it kept his coffee hot for the whole day. So far so excellent. He tends to chuck them around in his van so wanted one that lasts, this looks made to last.

The flask is great
