I so wanted to love this product, however it is simply defective, and the company will not even reply to my kindly notices and complaints. You'd think that not much could go wrong with such a basic design, but the lid continually leaks. Their so-called "customer service" refuses to even reply to my many e-mails. I am a very disappointed buyer.My advice is that you DO NOT PURCHASE ANYTHING FROM KLEEN KANTEEN.
