    Shipping Failure - Empire Fixed Immediately!

    Posted by Unknown on Jul 25th 2019

    Items were ordered and shipped out from Empire. Shipping company lost items in their warehouse or another location. Once I notified Empire of this, Ben immediately contacted the shipper to ask why there was a delay in shipment. Once he found out that the package had been misplaced by the shipping company, he sent out another duplicate order. The products they have are very well made also.

    Grinding Wheel

    Posted by Tony H. on Jun 15th 2017

    I purchased these wheels for our maintenance department and so far the have been very pleased with them and actually say they seem to last longer. Ordering was easy online and the items were shipped and received very quickly. No complaints, and the price was competitive, I plan to order from these folks again when needed. Thanks for great service and a great product.
