I ORDERED THIS ITEM AND NEVER RECEIVED IT. IT WAS SHIPPED USPS AND SCANNED INTO THE LOCAL POST OFFICE BUT BEYOND THAT I CANNOT GET ANY FURTHER PROOF OF DELIVERY. I HAVE CONTACTED THE DESIGNATED SHIPPER FOR ASSISTANCE AND HAVE GOTTEN NO REPLY. I HAVE HEARD FROM CO-WORKERS THAT THIS ITEM IS VERY GOOD FOR THE PRICE PAID, BUT AS OF YET I CANNOT VERIFY. PATIENTLY WAITING FOR CLOSURE.
