Kenwrote a review of YETI Rambler 30oz Tumbler on January 6, 2019
Familiarity: I've used it once or twice and have initial impressions
This is the worst cup, tumbler made. It leaks terrible. Good luck trying to drink from it as it leaks hot or cold all over your clothes and body. Dicks Sporting Goods sells the terrible yeti and refuses all refunds. It would probably put them out of business.
