I'd be wary of the knock offs because of the inner coating. I know the sigg has been tested and has I think test results if you write the company. Also Kleen Kanteen does too...the test results are actually printed on their website. With all the leaching going on..I'm very wary of companies who don't put it in print what their product does with the inner linings.
