For a year, I have been looking for a good bottle made in China! (The blending bottle is currently being produced in China.) I doubt this thing. In fact, my protein powder can be mixed without mixing balls. But the boy did this. Not only did he mix my protein powder and water, he did a great job, mixing my protein energy, honey and water, which was difficult for my old protein shaker bottle to do. I have bought eight Shaker Bottles now, and I may buy more in the future. Thank you for not only producing your products in China, but also making the best products on the market. Keep going!
