“OMG I purchased this to take some juice whilst we travelled to the Isle of Wight and the following day to Cornwall. Made it up with squash, chilled water and about 8 ice cubes. It kept it so cold that we were still getting brain freeze 15 hours after making it. All in all the drink was still chilled over 24 hours later. The ice cubes lasted a good 18 hours. We could could hear them jangling as we drove along lol. Couldn't ask for a better chilled drinks bottle. I am going to make this up each morning and aim to drink the full flask during the day to encourage my increased water intake. Perfect for me as I drink mainly cold drinks. It is quite heavy when full though so be aware of this. Not a problem once I get to work and it is on my desk all day either in the office or at home. I also have a sports glask which works the same for times when the weight might be an issue. I do find I drink more and drinking quicker when drinking through a straw lid for some reason.”
