Klean Kanteen Avis 

Paid £45 for the tk pro, looks great, pity it doesn’t keep your coffee hot for more than a few hours. Wish I’d stuck with Thermos.

Håller inte drycken varm särskilt länge. Jag hade väntat mig bättre!

Ordered an insulated tumbler and pack of straws and really pleased with them. Delivery was really quick and well packaged.

Ganz schlechte Kommunikation. Man bestellt, hört nichts und auf Nachfrage kommt ein "Sorry, nicht lieferbar". Unmöglich

Very satisfied with my kelan kanteen. The liquid inside indeed stays cold/hot for hours even overnight.

Purchased the 532ml classic steel water bottle however after the first 2 uses the bottle has started to develop an awful smell after c.30 min of being cleaned and filled with water. I also have the larger version purchased over a year ago but have not had this issue with it at all. Despite contacting customer services multiple times to report this problem I have had no response. Thoroughly disappointed by the bottle and the lack of customer service.

Habe eine Sportflasche geschenkt bekommen nach ca 2 Wochen hat sich die Dichtung von selber gelöst auf Anfrage zum Kundenservice kam das ich selber es bestellen obwohl es 95 Cent ist +Versandkosten)

Kundenservice lässt wünschen das man bei klean Kanteen nicht sagen kann.

I've had my Klean Kanteen with a sports top for a few years now, and it has leaked from the beginning.

So I use it as a nighttime bedside water bottle and never take it in a bag anywhere, which is ok for me but kind of defeats the purpose of having a "sports top" water bottle.

The design flaw is in the air valve, separate from the pop up sipper, although it must be said that the supper lid cover doesn't fit on the sipper well either.

The whole sports top needs a complete redesign.

I'd love to give Klean Kanteen a better rating but, in truth, your product kinda sucks. Fix it up, guys!

Bought a comparatively expensive tk pro early last year. The build quality and finish are better than most but there is a fundamental design problem.
This vacuum flask comes with an insulated cup but the stopper that seals the flask is not insulated. The heat loss from the stopper when you are using the cup is substantial. If you don not replace the cup back on the flask it cools down very quickly. I have to decant any hot drink from the flask into a separate insulated cup, which is a nuisance. I emailed customer services at Kleen Kanteen and got no response so I do not know what their explanation of this apparently seriously flawed design issue might be.

20 Hours my a.. 45 minutes approximately before the beverage was already lukewarm. otherwise nice for cyclists with the 3.0 supply,

Tyvärr inget jag kommer köpa i framtiden om de inte utvecklar produkten, den läcker väldigt lätt, håller inte tätt från korken. Den håller kylan VÄLDIGT dåligt. Jag åker hemifrån runt 06:30, nyfyllt med kallt vatten, vid rasten omkring 09:00 är vattnet inte kallt, utan ljummet. Produkten i sig är fin utseendemässigt, men testar man denna produkten ett tag så är den inget att rekommendera för mig. Upp till var och en att testa produkten så min recension kanske inte faller alla i smaken men det är min åsikt om produkten.

Bought one for christmas and have used it every day since. Keeps water pretty cool and fresh and the nozzle is really easy to drink from. My favourite water bottle i've ever had.

I bought a bottle from Klean Kanteen - It's very stable and looks beautiful, but it's unfortunately very expensive. Furthermore it was very difficult to open it. So I bought a different capping from Klean Kanteen, but this was leaky.
