Title: Simply the best tumbler.....period
Review: I've owned two of these for years and they're still as functional as they were when they were new. They've been abused - dropped, washed in the dishwasher, knocked over - and the only difference is the dents that have been caused. They still maintain a tight seal and keep beverages very hot. I've given them as gifts to lots of people and everyone has always been super impressed with their insulation quality. I'll sometimes use a plasitc tumbler outside to save on the abuse my Nissan has taken, but it's not worth having your coffee get cold in 15 minutes - especially in the winter. I'll never buy an insulated tumber other than Nissan!!!
