I've made several orders from this company. Each one was handled and shipped quickly and the status on backordered or preordered parts communicated well. At one point a part in an order was damaged (from the manufacturer) and KB-3D quickly sent a replacement. This company has earned my repeat business by providing good quality parts at reasonable prices and offering exceptional customer service.

Ordering was quick ans easy, the website was easy to navigate and my order was shipped and arrived sooner than expected. I'll be ordering from KB3D again and referring friends as needed.
