4035.232.050 Ultralight Thermos Flask, Black, 500 ml, Extremely Lightweight, 210 g, Drinking Bottle, Dishwasher Safe, Thermos Flask Keeps Hot for 10 Hours, Cold for 20 Hours, BPA-Free

This is the ideal size (750ml) for the Huel drink/meal I take to work, made with 500ml of water. The built in pouring/drinking spout is easy to use and comes apart to clean. Being stainless steel the whole thing is food safe, strong, and easy to clean. Keeps my Huel chilled until I need it, haven't tried anything hot yet but I have confidence it'll be fine. So much more practical than the old glass thermos flasks I remember.

Excelent product and service

Perfect to take on a walk with coffee bags. You can brew a decent cup of coffee from your chosen bags confident the water will be hot enough to brew. It's surprisingly lightweight too. I have a titanium mug but this flask has no cup/lid, not a problem for me, but might be for some. I also like the locking lid and the pouring action.

Very efficient thermos keeps drinks hot for ages. No cup with it so you either drink directly from the thermos itself or bring your own cup. I found drinking very hot coffee from the 'shaped' spout to be uncomfortable as you cannot control how much you sip. Otherwise, happy with purchase.

This keeps coffee warm all the working day, it's lightweight. I prefer to drink out of a cup as I find the flask not easy to drink from directly. Shame a cup is not included.

I've been through about 5 different flasks and this is hands down the best. I made a coffee in it before work this morning and when i got home I went to drink from it expecting the usual luke warm remnants... and burned my lip! This thing has lost maybe 5% heat in 7 hours. It's actually insane! The lip is perfect for sipping. The outside of the flask remains cold with barely a hint of (escaping) warmth near the top. It fits in my car cupholder with ease. This thing beats all previous flasks hands down. (I never write reviews on here and here I am waxing lyrical about a thermos. Lol!)

Fantastic value for money. 5 hours after putting coffee in this thing and I still have to drink carefully. That by no means is a negative, that’s what I wanted. It really works. What can I say, my other flask from years ago must have been seriously rubbish as this is amazing. Go get it, its brilliant. Love the little lock feature also. Other people in my house want one as well so I am ordering 2 more. Very happy with it as if you needed clarification. 😊

This is a well designed and manufactured product. The locking mechanism looks a little flimsy by works adequately, at the moment. The capacity is 75ml - that's about three full mugs (not just cups, mind you). It insulates hot fluids fairly well but there's a definite 'tail-off' before the end of the stated 10 hour duration for heat retention. However, this compares fairly well with similar products. I haven't tested its retention for cold liquids as it's not something I'm likely to require. A reasonably priced product for this level of quality.
