Yeah, I know everyone's tired of hearing about this...but it's bugging me--big time. I sent a follow-up e-mail to Klean Kanteen to ask them if the potential steel fragments they mentioned in their previous e-mail to me would cause any health risks. This is their reply:
The stainless on stainless friction may lead to a small amount of stainless residue getting into your beverage after a prolonged period of time. We have done testing of screwing and unscrewing the caps thousands of times on a dry bottle, and didn’t find any residue at the bottom of the bottle. This was basically just a precaution that we made because we had a large customer of ours point out this possibility to us.
The polypropylene on stainless will not cause the same type of friction as the plastic is more forgiving and won’t break apart like the stainless might.
I don't really know what to make of all of this...they did plenty of testing and never had a problem...which leads me to believe that this was primarily a cost cutting measure that they readily adopted when they thought they had a good enough reason to...
I know that some people are able to buy the lids and the bottles separately, but the only way I'm able to buy Klean Kanteens in my area is via the internet. The bottle comes directly from the company's website now with an all plastic cap--you have to PAY EXTRA for a stainless steel & plastic cap if you don't want the plastic touching your drink. Prior to January of this year, the Kanteens came with a stainless steel cap at no extra charge. Well, I'll shut up about this now...I know after 3 posts about it, people must be tired of it. I just hate to see a good product that I used and a company I respected...go down this path.
