I like the look of this bottle and the size is perfect. However, despite the "leak proof" top, it still leaks if placed upside down in my bag. I was quite disappointed. Overall a nice bottle, but quite expensive for something that still leaks. 3 stars

I'm extremely picky when it comes to water bottles. What I like about this one: reusable c aluminum, .75 L size, and the quality seems like it will stand up. However, it is sometimes hard to drink from, the outside gets really chilly, and it's a bit hard to clean out as well, since the mouth of the bottle is small, and the sport top is different. 4 stars

This is an upscale designer sport water bottle, top of the line, and so much fun. The designs of all of Sigg's water bottles are gorgeous, from the plain, solid color bottles, to the ones with intricate designs.

I switched from regular plastic water bottles because of health concerns, thinking it would take more work to maintain. These do necessitate regular cleaning (I clean mine every day), but having something so beautiful to drink from makes the cleaning less of a chore.

Sigg of Switzerland water bottles are very high quality, made of light aluminum on the outside, slightly insulated, and covered with a special powder coat on the inside that prevents any leaching whatsoever, unlike plastic and polycarbonate water bottles. They are light, durable, and perfect for any activity. They do dent, but this only affects the outside, and I am told that for Sigg fans the light denting is more like a "seasoning" of the bottle (this is how I regard it); at any rate, my dents so far don't affect the inside of the bottle at all---they are just on the outside.

Sigg bottles come with several different types of tops. Although this sport bottle comes with a sports top, I didn't like it, so I bought the screw top. I don't like sports tops in general because you leave them on while you drink from them, and this one was no exception. All of the Sigg tops are interchangeable and if you don't like your top or if you want variety you can buy extra/alternate tops (from Amazon). The bottles are totally leak-proof with the screw top as well, which is important to me.

They are also expensive, but they are so durable that you can plan on them lasting many years. I consider them both an accessory and an investment in my health, so they are well worth it value-wise for me.

Highly recommended.

Bottle is slender enough to fit into cup holders. The sport top took some getting use to, but now am use to it. You do need to wash it often with soap and water, then let dry out completely. Also, found out from the instructions that it's not for long term storage of water. Also, dents when dropped. I am still happy to have a non-leaching bpa free water bottle. :-) 4 stars

It's very convenient, sturdy and completely leak free. I like the fact that it's metal, because plastic bottles are considered to be unhealthy. 5 stars
