BEWARE!!!!!! Terrible service. was sent damaged toner CPU unit and returned it right away. Took 4 weeks to get a credit issued to my card, however, I am pretty sure it still not has not been done as it has been over 5 business days and the credit has not appeared and they have not sent me the credit card receipt of the credit - which I have asked for. Seems VERY shady and it looks like I will have to dispute through my actual credit card company.
