Bests & Worsts Reviews from Amazon

I've had several of the regular Klean Kanteen bottles which are great, but I always disliked the fact that the liquid didn't stay cold for long unless the tote was used, and the bottle would sweat quite a bit. I didn't like the tote because it smelled odd and made the bottle awkward to set down on tables. When I saw the insulated bottles I bought 2 of the 20 oz size, one with just the regular loop cap and one with the cafe cap. I have to disagree with what everyone has said about both caps. I love them both! I use the bottle with the loop cap the most, and it keeps my juice cold all day, 9+ hours at work, even without adding ice. The cafe cap doesn't leak for me, either out the opening or around the seal. Of course, it does state that the opening you drink from isn't supposed to be leak-proof, it says it right on the packaging. I don't upend my bottle, but if I did, I might get a few drips at the most. These are great as travel mugs for coffee, they even fit in my car's cup holders. I don't think most travel mugs are completely leak-proof anyway, especially if you can drink out of the cap. Keeps coffee hot for the whole day, just as stated. Would also be great for smoothies or soup. I plan to buy a couple of the 12 oz size for my lunch bag. Another excellent product from Klean Kanteen! Update 10-8-13 I just wanted to say that these bottles are still going strong after daily use, almost 4 years later! We have had absolutely no problems with them, and my husband even puts them in the dishwasher despite the fact that you are not supposed to. I'm back to buy another one!
