Appearance material The appearance material is quite high and beautiful, and the sponge feels more comfortable than plastic. Although the handle also has plastic parts, it doesn't have that kind of plastic feeling and the workmanship is very satisfactory. What I like most is that this button is in Chinese, which is easy to understand, simple to operate and advanced in carrying function. Can count calorie consumption, set countdown and countdown. You really have to believe what you want, and the dual-purpose switch is also very advanced.
