Review on Premium Stainless Steel Protein Shaker Bottle with Marker & Shaker Ball - 30 Ounce Sports Water Bottle by Cliff Gibs

This shaker works very well. I like that there is a silicone ring on the lid to keep it from leaking. I also like that it has dimensions on the inside. Also, mixing was very easy and no powder was left on the bottom or lid. However, I have a few issues with this bottle. First, the lid is quite difficult to open and remove. If you suffer from arthritis or carpal tunnel syndrome, you probably cannot use this bottle. In addition, it does not have double walls, so there is a lot of condensation outside. Another thing is that in their description it is written that he had a retractable lock, but he does not have it.
