New Wave Enviro Tinted Stainless Steel Water Bottle (0.6-Liter, Green)

I don't like the screw on cap too much - takes longer to screw on and off than traditional water bottles, but it serves its purpose.

The threads on this bottle are entirely too fine and not carefully crafted. No matter how carefully I thread the cap I end up with very fine slivers of the plastic cap floating in my water. So, instead of chemicals leaching from my plastic bottle into my water, I can consume the plastic directly.
The bottle cap design also makes it rather slow and tedious to replace the cap without thoroughly shredding the plastic threads.

I like this bottle; the size is just what I needed, and the color is durable. I think this type of finish is preferable to the opaque paint-type finishes you see out there. My only (and small) complaint is that most times, the lid does not want to thread correctly; you have to slowly and patiently turn the cap. Not good for someone who doesn't have the patience to do that every time. I just get the feeling that the plastic that the cap is made of would not be able to handle multiple incorrect threadings. Maybe it could, but I like the bottle so much I am not willing to take the chance.

nice size ss bottle for general use. but they use a plastic cap with fine threads so you must be careful not to cross thread. One of the 5 bottles I received had bad threads and is very hard not to cross thread wear as the others are not as bad but could be a problem in the future. The 40 oz bottle uses stainless cap with large threads which I think is the only way to go after comparison.

good luck!

I bought two of these. One started leaking from the base within a week and the lid didn't fit properly on the other.
