The product corresponds to the description on the store's website. The power supply has already tried-everything is fine.

AND the opportunity to adjust voltage proved enjoyable бонусом. Order delivered in 18 days. The track was tracked across russia. The seller was not even lazy to specify the code of the new track-which changed after delivery to russia. and passing customs
