SiggThermo Flask - Hot & Cold ONE Insulated Water Bottle - With Tea Filter - Leakproof - BPA Free - 18/8 Stainless Steel - Grey - 0.3L / 0.5L

great design, easy to drink from and keeps the contents so cold, or hot if that's your requirement, I put warmish water in one and put it in the fridge thinking it would cool it down and the bootle was so well insulated the water was still warmish a few hours later

Keeps things hot and cold for a long day out and about.Top and seal work well.

Bought the electric blue bottle, feels very well made with a nice soft powder-coated finish on the outside. Colour's not as neon-blue as it looks in the amazon images.The wide-opening mouth makes it easy to fill with ice or fruit. The lid feels well made and easy to use one-handed, though the button to open the lid is a little stiff. It's also easy to clean with no straws or small holes to breed mould/bacteria/etc. The bottle fits my normal-sized car cup holders well.You can position the drinking spout in three different locations so you can drink from the front, right or left. This feels like a slightly odd and unnecessary design - if the spout was the same shape all the way round, you'd be able to drink from any angle without having to remove and reposition the spout!The strainer is small and plastic and was difficult to get off. It doesn't give you a lot of space for fruit or tea bags and the hols are too large to allow you to use loose leaf tea. Don't think I'll be using it but the bottle works fine without it.Drinks keep cold really well - half a bottle of ice cubes will easily last 12 hours or more without melting completely. Haven't used it for hot drinks but insulation is certainly effective so should be good.

Lovely color, keep the temperature cold or hot for such a long time. This is the second I have would highly recommend.

Great little on the go flask for hot or cold drinks. Easy enough to unscrew and fill up.Found it kept my drinks hot for easily a couple of hours which is more than enough for me to finish my drink for the size of the flask.2 enhancements I see (hence the 4 star). The tea filter thing is some what tricky to get off, its quit thing plastic so worry how long it lasts so could of done with a better design to remove it.The second is the lid, the design is good however the plastic doesn't feel quality so when trying to unscrew the top again I am careful not to break it.So far been using the flask for a few months and have had no leaks or problems.Side note, if you are worried about the lid you Sigg do a more solid hot/cold screw lid for about £5.00

Was great when I got it. But after awhile water got into the casting and I can't get it out. So don't use it anymore.

I bought this bottle for everyday use , and I use it at work , I'll sum up pros and consPros- keeps liquid cold for an extremely long period of time- drinking nozzle is odd however is actually excellent- design and overall build is very good and very attractiveCons- black finish wouldn't last a day , I've wrapped mine in amalgamating tape (idea from another reviewer) to protect it , which works well- lid/top has come loose after 5 days usage , will need to be replaced within 2 weeks for sure , and at £10 for a like for like replacement , is not a viable option long termMy advice : for casual use or if you don't work outdoors , this is perfect , genuinely excellent. But if you use this outdoors or have a more gritty lifestyle this will need some upgrades (tape wrap and a non flip top)Overall I would buy this again.

A beautifully made high quality product, I love mine.
