heavy duty...recommended
BEWARE!!!! WORKED FOR ONLY 3 DAYS!! SELLER SENT OLD CIRCUIT BOARD IN NEW CASING. THE CIRCUIT BOARD HAD ALREADY BEEN REPAIRED BY SELLER. CIRCUIT COMPONENTS HAD BEEN REPLACED/REPAIRED. SELLER REFUSED REFUND ALTHOUGH ALL PROOF WAS UPLOADED. IF YOU HAVE ORDERED, OPEN THE CASING AND CHECK THE BOARD. SEE PICTURES FOR PROOF. VERY DISAPPOINTED. WILL NEVER ORDER FROM THIS SELLER AGAIN.
