    Good Cup, TERRIBLE Seal

    When I bought this shaker cup, I SPECIFICLALY bought it because of the stainless steel - naively thinking it would be durable. Now, whenever I try to ***** the lid on, it screws on fine, but when I shake it, GFuel goes everywhere. Terrible seal. Would not buy this cup style again.

    Would be better if the clip didn’t immediately break when I picked up by it. The straw is a nice feature but if it’s not pushed down all the way the small cap doesn’t close and the when it closes it just pushes the straw to the bigger opening.

    Not so sure about the straw

    The straw is just a silicone tube you have to thread through the hole every time you want to open/close the lid so I just don't use it, it's not a built in straw like you'd expect. The shaker overall is really solid though and keeps your drink cold for hours.
