Rated 3 out of 5 by from THE GLUE! I would give this a 5 out of 5 if ONLY they didn't use some sort of super glue to glue the paper label onto the bottle. THERE are TWO Stickers, one with the barcode on the bottom, and one for the paper around the bottle when you first get it. When you remove either labels, you are left with a film of sticky residue that is IMPOSSIBLE to scrape off. I've tried oils, baking soda, soaking in vinegar, shaving it with razor. It only minimally reduced the stickiness, but ultimately its still there, being stick. What's worse is that I bought 3 different klean kanteen bottles/cups, and they ALL had the same issue with the glue used to stick the labels on.

Rated 5 out of 5 by from Fine tool for the job. This is a very durable bottle for room temperature liquid applications. If you want the water cold go thermal. The sport cap leaks a bit but not a problem if kept upright in your pack. The loop lid is bullet proof and ideal for day pack, golf bag, or any application where the bottle gets thrown around or left on its side for extended periods. Very lightweight when empty. Easy to clean. The carburetor on the sport cap is rather noisy when dispensing unless you use a finger to muffle. Sounds like your sucking that last bit of shake from the bottom of a paper cup. Still a 5 star product when both caps are available for specific duty.

Rated 5 out of 5 by from Amazing!! You should totally buy one! The Klean Kanteen company sent my class 30 classic 18 ounce water bottles! In our computer class my teacher told us to write a letter requesting products. I choose this company because I love all of there products. The next week they sent me and my classmates water bottles. I wrote them back with a thank you letter and now I am writing a review. We tried them all out and everybody loved them! They loved the mouth and how it was sealed very nicely. We only have 1 little recommendation, the water bottle gets really cold when you touch, Yes I get it you can get insulated ones, but if you put ice water in them, they get very cold. Otherwise they are perfectly fine and I totally recommend them for everybody.

Rated 4 out of 5 by from Great purchase Love this bottle, the only things I don't like about it are mostly my fault. I ordered this bottle for coffee not realizing that it wasn't insulated, and it gets VERY hot (or very cold depending on what is inside) and it hurt to touch (the instructions that came with the bottle said don't put hot liquids in, so it's not like they don't warn you, but I didn't see this on the website,) however this was an easy fix with ordering a $2 bonison water bottle sleeve on Amazon. The bottle also sweats a lot with cold water, but the sleeve helped that too. Other than those two aspects, no complaints with the bottle. Really really great purchase, and very fast shipping.

Rated 5 out of 5 by from The best bottle I have ever bought! If you are consderinf buying a Klean Kanteen I emplore you to do so. This was my first Klean Kanteen that I bought and I loved it so much that I bought 3 more. I have recently bought the insulated Klean Kanteen and I can assure you that it will keep your drinks colder longer than any of the competitors will (and I have used them all). One of the most notable parts is the solid silicon o-ring that seals the bottle. Along with it assuring that the bottle is leakproof, it makes sanatizing the bottle way easier due to the lack of small unreachable places for bacteria to grow. All and all, if you want the BEST bottles Klean Kanteen is your only choice. Awesome company and amazing products!

Rated 1 out of 5 by from Disappointed with leaking and unsanitary top I am forever in search of water bottles that will fit in my teenagers' lunchboxes that don't leak. I was hopeful for these 18oz. Klean Kanteens with the sport caps, but was very disappointed. The kids complained about the water bottle leaking all over the lunchbox and also about the wanting a cover for the spout (because the inside of the lunchbox is not always so clean...). These water bottles failed on both of those fronts and unfortunately I had bought 4 for $80. Complete waste of money.

Rated 4 out of 5 by from Branding Klean Kanteens are well known for their exceptional durability and usefulness. The Classic 18oz is the perfect size for quick liquid hauls, whatever they may be. I don't have to worry about spills and all the scratches acquired over time only enhances the appearance of the Klean Kanteen; which is why I think the logo could be printed smaller on the bottles. At this point, the product speaks for itself. No need to blast the branding. A more subtle approach to printing the Klean Kanteen logo on the exterior is a tasteful and radical way to approach product awareness.

Rated 1 out of 5 by from Sport top leaks I received this Klean Kanteen in May when I participated in a hiking adventure trip with National Geographic Travel. The sport top leaked immediately from the air-flow nib. I have repeatedly contacted Klean Kanteen customer support seeking a replacement or repair for the top, but they have not stood behind the warranty. Disappointing results and service.
