Okay, thank you for your criticism and correction ~

Can you tell me your opinion ~

The so-called all kinds of man-machine are bullshit, and the relevant provisions of the national standard. Several important issues are that cost control, long-term users will not have too many, the grip comfort of the handle, the user will use the power of crutches in the process of sitting down and standing up, all handles will have to be consistent left and right (their own brain mends the picture, so the strap design is very chicken ribs), the overall weight must be light, the crutch storage and placement will not easily fall down, etc. Next is the overall appearance coordination, surface treatment of these icing on the cake.

Fortunately, the structure is not too complicated. The usage is very simple.
