Gaucho BrunoStainless Steel 1 Litre Bullet Flask for Drinking Yerba Mate | with Iconic Red Spout for Precision Pouring| Durable | No Handle for Easy Transport

after using 6 months . there is many dots pf rust . it is not stainless steel !!

Initially I thought it wasn’t too bad. The pour is rather sporadic, presumably due to breather hole being too small but it was still usable. After a few weeks though the spout started leaking at the base of the ball joint, which was messy and not pleasant getting hot water dripping on you. Shortly thereafter the flask started transmitting heat and the water lost it’s temp very quickly.All in all, a poor design, poorly made.I ended up buying an established brand flask with a traditional glass liner for a fraction of the price. Maybe doesn’t have the fancy spout but it works!
