Shipping month, with other items everything is always fine, and with STM there are problems, of 2 pcs. One is defined normally PID (H) 0420 is stitched and working, the second is defined by PID (H) 0410 is stitched and does work accordingly because this PID corresponds to another controller. Two months ago took from 2 pieces also only one worker. The seller to my question on the previous order so did not answer anything, so reduced the rating. Only 50% of working controllers are obtained.
