Portable Blender, Cordless, 18oz. Vessel, Personal Blender

Pressing the power button twice quickly works. At first, I was confused because I didn't know how to use it, but after trying various methods, I figured it out. The sound isn't too loud, which I like, and the design is also nice. I think I'll use it well. The cost-performance ratio is good too~ I feel happy because I bought it at a low price.
