Great. The goods are exactly as stated.

T**r 06/03/2020

Module working. Wifi network banit

The seller quickly sent the goods, but the delivery was well, very long (almost three weeks). Because of this, the seller himself extended the protection of the transaction, for which he put five stars. Track is not tracked.
