I bought some of the SIGG bottles during the last wootoff - it was a two pack I think and I got 2 orders. They all leaked all over my kids’ backpacks the first time I packed their lunches. SIGG’s insulation may be good, but their water tightness sucks.
Found one of these at Goodwill a couple of weeks ago. In perfect shape. No box, but it looks unused. This is the only place I could locate a picture of an even similar model.
Maybe some other wooter in San Jose bought it five years ago and never used it?
