Pros:-

• Free app so no need to pay extra after buying Yeehaw Wand
• Can design directly on phone or tablet so can be quite portable when need to use it on the go
• Can use a 3D printer to print out the 3D design

Cons:

• sketching in mid air can be quite tiring for our hands after some time. (Can train arm muscle at the same time)
• Some of our hands tend to shake as not used to drawing without our palm on the table like normal writing or drawing. Just need to get used to it.
