Soldering excellent, no flux and solder balls did not find, the place of soldering glitters, all the elements are missing!

Shawls received, checked, stitched. quality is good. stitched St-link OM. came in one parcel with other orders.

Everything is fine, just programmer come a little crooked, but that's okay-the main work. Soldering accurate.

Fast delivery, by the kind of chip clone, I'm not very in the topic, just information for prepolated buyers.

Very pleased. The price for the finished product is lower than for a separate microcontroller.
