We found out that dropping the SP20 package may cause the boards to shift.
We got complaints from about 2% of non palletes customers. Most of the units can be fixed at home by replacing the boards.
We halt individual package shipments for one week, until we'll solve the issue.
If you got such SP20, contact support@ for miner assembly guide. If the SP20 was actually damaged, we'll RMA.
