Best shaker cup I have ever owned. Can't beat it for the price. I've always had issues with the lid on my past shaker cups being hard to open and eventually tearing, but the way this one is designed is perfect.
Good quality
Now I can drink my Level-1, Phormula-1, Opti-greens 50, and Megawatt from a sweet 1P shaker! It gets the job done in style!
Love this shaker because of the insert that helps mix and break down any lumps of product. The color is nice too.
The answer to this question is heck no! I received this shaker as a prize for a fitness competition and just like all 1stPhorm products it is incredible! No leak, easy clean, and none of that sickening plastic/chemical smell you get with some new shaker cups.
