I received two metal bottles from I ordered from Amazon. A Sigg and a Kleen Kanteen (KK).
The Sigg is 1 liter and made out of aluminum. The diameter of the bottle (3.15") is slightly too big for my car''s cup holder, but fits my fanny pack pockets. The outside has some cool purple paint (comes in different colors/designs). There''s a coating on the inside to protect the water from the aluminum; this coating is proprietary, so they won''t tell you what it is. It does say not to use the bottle for long term storage, which makes me nervous, as does the aluminum.
The KK is 27 Oz and made out of stainless steel. The diameter is too small for the car/fanny pack (rattles around), but fits nicely into a bike bottle cage. The 27 Oz is less than I prefer, but is probably OK for most purposes.
Both seem like high quality items, which they should be for $20 each. Both have loop top screw on caps (KK has other options too) with gasket seals. KK''s top is made of stainless steel on the side that touches the water, whereas the Sigg has a plastic top (nylon?). The top on the Sigg has a fine thread, which can cross thread more easily. The size of the opening on the KK is larger, which I like. Both have a smooth edge that''s easy to drink from. Both pass the turn upside down test (no leaks).
I rinsed both out with hot water several times, then put distilled water into each from my Waterwise distiller. The KK does impart a slight metallic taste, whereas I can''t detect any added taste from the Sigg. I can also smell the metal from the KK. I don''t know of any health problems from stainless steel, and in fact my distiller is made from stainless steel, so I''m not sure what to think about the added taste. It may be more of a smell than a taste from the KK, since when I pour water that has been in the KK overnight into a glass, there is very little taste difference.
If KK made a 1 liter bottle with the standard diameter (about 3 inches, like plastic bottles), deciding which to use would be a no brainer for me. With the different trade off''s, I''m not sure which I''ll end up using, but probably the KK; the aluminum and coating just seem like they have too many potential health problems over the long term. KK does make a larger 40 oz bottle, but the diameter is too big for me at 3.5 inches.
I''ve been lusting after an aluminum water bottle for quite some time, and finally got this SIGG. I am very pleased, so far. It comes to work with me every day. True to the descriptions, your water will taste neutral after being in this bottle. I have not tried storing any other liquid in it, however, and so cannot testify to its taste properties with juice or anything other than good old dihydrogen monoxide. I would recommend this bottle to anybody, however don''t go bashing it around like you can with a Lexan bottle. Aluminum can dent fairly easily, but that''s the price you pay for lightweight. SIGG Switzerland rocks!

I thought I had finally found the perfect water bottle. It was made of a non-leaching material, it came in a larger size than the average water bottle, and the design was stylish. Unfortunately, it has not lived up to my expectations. Be sure to screw the cap on VERY TIGHTLY or you will have water all over your gym bag or car seat. Also, keep a firm grip on it at all times since it can not handle a fall to the floor without sustaining considerable damage. I dropped the bottle once and it is now dented on the bottom. The impact made the bottom pop out so now it wobbles on my desk. This is not a cheap product so I expected more from itespecially since I have only owned it for about three weeks!

Love my bottle, use it all the time; it is a really beautiful object. Bought the kids some too, don''t know if that wil have turned out to be a good idea, still better than them drinking out of plastic.
Two caveats:
1) Not dishwasher safe and Hard to figure out how to clean (I just purchased Sigg''s specially designed brush--hope it helps)
2) Not terribly scratch and dent-proof.
I''d go to 5 stars if:
