Vacuum Insulated Double Walled Drinking Bottle, Water Bottle 750 mililiter Leakproof 4 Caps for Sports, Fitness, Outdoor, Work,Children or School/Thermoflask/no BPA

Ihave no opinion, the product was purchased for my great granddaughter who likes it.

I've never used a flask before, but I was looking for something to take into college with me. I normally buy a diet coke for lunch, but buying small bottles every day gets pretty expensive, so I wanted to save some money by just taking my own.I was a little sceptical at first, but I filled the flask with ice and coke, and when I opened it 5 hours later, the ice was still there! It hadn't even melted. The coke was freezing, more so than it was in my fridge (not not solid or slush). It was wonderful. I checked again when I got home and the ice was still there in full! That's 10 hours!The bottle itself feels premium and great quality. The various lids work well for each type of drink. You even get two nice straws and a little cleaning brush, which is good as it can be a little tricky to clear the sticky coke from inside of it.Not tried with hot drinks, but I imagine it holds heat just as well. Probably best to go with the metal lid for optimal temperature keeping, but I've not tried the other yet so maybe they work just aswell.

As to date the flask look well made and a tough construction. It comes with plenty of top options. It is lightweight and finished well. I have not tested it with hot or cold liquids so unable to confirm how long they will stay at the required temperature. Delivery was prompt and well packaged. I thought it was offered at a reasonable and competitive price. So far 5*.

Nice construction. I found only 2 of the lids useful. I have a Stanley drink container that has a better, wider, lid that, when screwed on gives a useful opening for drinking out of. In hindsight i would get a second Stanley. This one is dufficult to get ice into.

Keeps hot stuff very hot (burn your tongue) for 3-4 hours. Best flask I've had.

Useless had to return and buy the ultimate thermos.No good for hot liquid...

Excellent
