Most of the parts are printed perfectly. The larger black pieces (control board and PSU cover) are much lower quality. They need trimming and cutting even to get them to fit together. The store said that's normal for the process which I'm a little disappointed about.

Pieces are nicely printed. Pieces are sometime different from the official Prusa Bear Upgrade on GitHub, so instructions are tricky to follow and screws and nuts needed may differ from the instrcutions on GitHub. The items were shipped really fast, but we only received them after 3 months. But it's COVID time and parcel seems to have been stuck in Canada customs or local warehouse for a long time, so not really store related.

The quality is good, very enthusiastic store. The print still has some defects, but it is well worth the money. It took nearly 3 months to receive the package, the time is too long because of covid-19
