This is an excellent stainless steel bottle which both my husband and I use daily. I bought the orange one; he uses the regular stainless steel. We used to buy tons of the plastic water bottles, drinking several a day, but wanted to cut down on our use of plastics. These water bottles work well in conjunction with my water filter system and the taste is clean and fresh tasting. Highly recommend them and this is a very usable size. 5 stars

After reading recent information about Sigg not sharing info about chemicals used to line the interior of their bottle, we opted to switch to Kleen Kanteen for the stainless steel. There are pros & cons:
1) obvious pro - the materials are known to be safe
2) the bottles sweat where as the Sigg did not sweat at all
3) the mouth of the bottle is large enough for ice cubes but makes it a bit more difficult to drink out of -- kind of like drinking out of a 1qt gatorade bottle --- sometimes a little bit dribbles out.
4) My 18month old loves his bottle because its the same color (stainless steel) as his dad's. We got him the sport top instead of the sippy top - and he manages just fine.
5) the slim shape fits nicely in most cup holders and water bottle carriers

Last month I bought a 40oz Klean Kanteen bottle and a 33oz Sigg bottle. In the end I prefer the Klean Kanteen.

Both bottles are very light and look good. The Sigg is lighter, but not so much to really matter. Sigg wins easily in the looks department with different artwork to choose from and the bottle I have has a nice textured powder coat finish compared to the KK basic look and smooth surface.

Sigg uses an epoxy to protect your water from the aluminum and tells you not to use the bottle for long term storage. Could be a bit worrisome not knowing what's in the epoxy and the possibility of aluminum contamination. I have not noticed a metallic taste from either bottle drinking straight unfiltered tap water. I prefer the stainless steel of the KK just because it's probably on the safer side.

The bottles are both lightweight and made of thin metal. I haven't dented either but I have been very careful with them. Both feel like they would dent quite easily. I have not scratched either bottle and the paint on both looks like new after daily use from work to the gym.

The KK bottle has the cap threading formed into the neck of the bottle while the Sigg uses a metal ring insert in the top of the bottle to thread the cap onto. Some people have complained that the Sigg's threaded insert is sharp, but I have not had this problem. The KK is more comfortable to drink from though. Also the wide mouth of the bottle makes it easy to put ice cubes in, which you can't do with the Sigg unless you have very small ice cubes.

I have the loop cap on both bottles. The Sigg I really have to twist the cap on tight so it doesn't leak. The KK cap seals quite easily and has never leaked. The KK also uses a thicker thread size and is easier to screw the cap onto because of this.

Some people are complaining about sweating. On a hot day with the bottles filled with ice cubes both will sweat, but plastic bottles will also.

If I was going to spend that much money on a water bottle again, I would go with Klean Kanteen without a second thought. The only advantage of the Siggs is the exterior design. 5 stars

We have 8 of these bottles. Two for Mom and Dad...two for our kids ages 2 and 4. They are indestructable, you can scrub the insides and not worry of scratching and they do not leach anything into your beverage. 5 stars

I LOVE this water bottle. It can go in the dish washer, it keeps water a little cooler, and it's pretty. My 2 year old daughter and I both have pink. Mine has a little dent but who cares? Best of all, it's eco-friendly and it has a wide mouth that fits ice cubes. The Sigg water bottles have a small opening and do not fit ice cubes. Buy this bottle for everyone in your family and quit putting plastic bottles in the landfills! 5 stars
