I've made a few projects with this kit from Adeept. The instructions are clear (with one or two typos, here and there). You have to clone a GIT repository to access the code in both Python and C. I kept the box for about two weeks before opening it. I don't know if this "bottled up" the factory smell. When I opened the box, there was a strong "oily" smell (I'm guessing it was probably the P.C.B. chemicals used on the phenolic boards when the parts were manufactured). It took several days for everything to air out. Make sure your work area is well-ventilated. No soldering required.
