Keeps hot drink very hot for 8 hours and I love the lockable cap

Product Specs; Height: 9.1’Inch Circumference: 8.1’Inch Diameter: 2.6’Inch Volume: 425ml Empty Weight: 290g The Basics: Not Dishwasher/ Microwave safe. Awarded only 4/5 as the temperature had dropped from boiling to drinkable in 4-5h, so would assume it would be lukewarm at the 12h mark. That being said it still works great for my need. This flask ticks all these boxes! I can run into the staff room, pop the flask open take a swig of coffee and flip the lid shut all with one hand. I brought this to replace my old coffee flask of a similar design. I work on a hospital ward with little to no time for a coffee so I needed something that keeps warm throughout the day and is quick and EASY TO USE. It was also essential for me that the mouth piece is sealed and has little hand contact, to prevent it being accidentally contaminated with germs. THE LOCKABLE top is a fantastic addition, I usually slip the flask in the side pocket of my bag which is then hurled into the boot of my car, while tackling several rounder-bouts on my way in the bag is knocked about in the boot. The lockable top stops any accidental opening and everything being drenched in coffee. ON THE MOVE, if you're looking to use this in a CUP HOLDER the measurements are Height: 9.1’Inch/ Circumference: 8.1’Inch & Diameter: 2.6’Inch. The product feels robust and well made, I believe it would be drop resistant from about 1 meter or so (waist/ counter height). The opening mechanism is simple and easy to use. Ideal for someone who might struggle with stiffer more fiddly tops. Outer of the flask remains ambient temperature and is not hot/ cold when held. The coffee tastes great and has no tampered taste from the metal inner that you often find with flasks. Which lives up to the statement of it being "Free of BPA materials, chemical toxins or metallic aftertaste transfer." I have used for both hot and cold drinks. I've pre-made FROZEN smoothies the night before then kept them COLD in the flask and decanted out the next morning (they're too thick to drink from the flask) I haven't tried with protein shake or soup but I theory the same principle would apply that they would be too thick, so simply unscrew and consume or decant if the rim of the flask is too hot. Easy to clean but *DO NOT PUT LID IN DISHWASHER* I've put the bottom flask in once by accident and it was fine, but I wouldn't recommend repeating it. The inside should be ok but the outer coating and build may break down. I simply fill with warm soapy water place cap on and shake lightly, carefully open cap as the pressure caused by shaking may cause a pop. Then let the soap run out the mouth piece and rinse. Wipe the mouth piece dry and store the flask upside down to drain.
