This is the fourth Helix cup I've bought. Love these shaker/mixers. Dona very good job mixing all protein powder up, plus they super quiet with no stupid metal ball. So glad my youngest son showed these to me .
As you said in the message above it’s been 15 days and I still haven’t received my 2 helimix yet. I also haven’t received any shipping updates or emails since I placed my order.
I loved mine, and so did my wife that she wanted her own. Definitely the easiest shaker to use, and no more clumps!
Wish you sold tops only. If I want another color top, I need to order whole new shaker. Good product though. Mixes well.
