I gave the company only one star because of there poor customer service. There shipping was excellent and very fast however I ordered the wrong product and that is where my problem started. I have been trying to just get a simple exchange but they never answer the phone and the never return my messages left on there customer service line. I have sent them numerous e-mails and only had one response. They never gave me a address as to where to return the toner cartridges to and no return authorization number. I just want a simple exchange that's all. But you just can't connect with anyone there. Very poor customer service. I suppose there products are good but lookout if you have a problem, good luck.
