I bought a Silipint in Bend a few years ago when visiting family there and loved it. Then recently I was thinking about a unique going-away present for a colleague heading to OU for grad school and *ping* the idea of a Silipint popped into my head. Right there on the website I found it - on sale, even! Ordered and received in great time. Of course, since I was on the site nd ordering anyway I decided to get another Silipint for myself (not an OU one, just plain) and two lids as well. She LOVES her gift and is taking it with her on an 8 week South American trip before she starts school, replacing a metal cup she was going to travel with. Success!
