This bottle leaks where the plastic lid meets the stainless steel bottle. I am not sure if it was a design error or this one was a defect. I complained to Primal Labs several times and they finally emailed me a return label. I sent the bottle back on 9/3/2020 and still have not received a replacement nor money back. They did give me a credit for sending the wrong flavored whey protein powder but nothing yet for the shaker bottle.
Great Stuff Really enjoy it
LOVE IT NEVER HAD STANLESS SHAKER
Does a great job at keeping my drink cold
Keeps protein cold for hours
