"Bought patch panels from them via their ebay store. But items received were different from what was pictured and advertised. They were very difficult when trying to make a return, and then claimed a short count when they finally accepted my return. Somewhat shady business -- you should generally avoid them if possible."

"Needed a mounting kit for a 2921 Cisco router. My usual supplier quoted $128/kit with a 2 week lead time. C&K had it in stock for $18/kit. Paid for the speedy shipping and had it by 10am the next day. Great communication too."

"I found these guys on Ebay, ordered a used 48 port Catalyst switch. They have a very advanced order processing system, excellent communication after the sale, and actually shipped my order next day air from the east coast to California for free (not sure if this was a mistake or not). Part was expertly packaged. Would definitely order from these guys again. Appears to be run very well."
