These Shakers are great, better than any others in the market. I did have an issue with mine and they responded that day and had a replacement shipped the following day. They awesome!
I got this mainly due to the fact I keep losing the blender bottle ball thingy. It mixes better than the blender bottle ngl. Wish there was a size for 1 liter though because I’d get that.
I already had a Helimix Shaker and i was convinced it's the best shaker out there, so how did i upgrade ? Well with the David Ziegler Signature Helimix Shaker. Still the best shaker plus you get a bonus boost of motivation by the kindest Bodybuilder David Ziegler ! Win Win
