ONEISALL 2L Flask,Insulated Stainless Steel Bottle- Thermo Flask with Drinking Mug for Hiking/Camping/Perfect for Hot Coffee & Tea(Blue)

Product turned up on time, i filled it with boiling water on Thursday at 5pm, there were no leaks and product seems good. Checked the water Friday at 5pm and its still boiling hot, checked again Saturday 6am and its still too hot to put fingers in. Not had a real chance to test it although ill probably only use it 4 or 5 times a year, the overall looks of the flask are good and it definately stays hot enough for drinks well past 36 hours. The overall build quality of the flask seems pretty good, but the plastic furnishings (handle and bump guards) seem to be made of quite a brittle plastic, i dont think this is going to be building site proof. I think so far this is going to be a great flask that will last a long time when used occasionally but i dont think its tough enough for everyday use and getting knocked about.

Great bit of kit . I'm using it for night fishing . Boiling water put in at 3pm was still boiling at 10pm . Cup is sturdy an great size . Love that you don't have to open the flask fully , just press the button an pour . Will be with me on every fishing an camping trip . An water was still boiling when I got home in the early hours of the morning . Had couple cups an washed down gear an still hot water left when I got home

As my heading, I think it's a good looking flask, but always leaked a little from the cap.It worked ok apart from that, but after a few months noticed water not retaining heatFor as long as it did when I first got it.The outside remained cold when filled with hot water, which showed it was keeping the heat inside.But when I found the water to only be like warm after an hour, I noticed the outside was very warm, afterAdding hot water, so the flask was not keeping the heat inside anymore, but releasing it almost straight away.I think the vacuum seal as failed? I don't know how?This flask never left the house and was kept on the kitchen work top all the time I had it.Also the top steel band came away from handle?I complained to Amazon that it had gone faulty, and fair play to them they issued a full refund, straight away.I believe there are a lot of good looking flasks coming here from places like chaina, which are just poorly made, andJust don't last. I will be buying Stanley, they don't look as nice but are tried and tested over many years, and comeWith life time warranty.

Had about 7 months, at first flask great ,keeps hot etc,now lid faulty and has leaked for a while, alot of money for a product that doesnt live up to the 5 star ratings

I purchased this flask as my sons and I have had frequent picnic lunches and as there are four of us the 1 litre flask only gave us one cup of coffee or tea each. This flask enables us to gave two each and the water in it stays very hot. It is a great design, is easy to use and has a very safe handle.

Had this flask 8 months now and it's failed. The water no longer stays hot and you can feel the heat escaping through the metal as soon as it's filled. So annoyed at £40 it should last longer. Do not recommend

I thought this was going to be a good buy. It’s sturdy, holds the heat well over 10 hours. But after only 7 months the retractable red button used for pouring has ceased to function. It’s a sealed unit to it can’t be fixed. It feels like the spring connection to make it pop up and down, has broken. I’m really disappointed as this wasn’t cheap to buy.

Holds more than a kettles worth. Having left the remaining water in overnight, I discovered still really hot nearly 24 hours later. Quite heavy but it is doing a great job.

Muy buena compra, mucha capacidad y muy fácil de transportar.

I’m happy with my purchase.

Conserva bene la temperatura delle bevande (provato con acqua fredda da portare in spiaggia). Non trovo così comodo il meccanismo di spillo dell'acqua con il bottone superiore (si incanta ogni tanto) ma comunque per robustezza capacità e tenuta termica è complessivamente un buon prodotto

I like the color and size of this flask. Instead of continually making tea, I make it once and drink it throughout the day. It seals well and keeps my tea warm. It comes with a carrying strap and my favorite thing is that the cup on the top is insulated so even if my tea is hot, the cup is not. It also has a button on the top to open the valve to let liquid through and the liquid come out the top very evenly.

purchased a few weeks ago, it is a good product overall, keeps water warm long enough, but the color of the handle does not look too good.
