Purchased 4 toner cartridges that cost over $200 a piece. One was defective. Returned it well protected, just not in original box because due to structural repairs in the office the original box had gotten thrown away. Even had an RA (Return Authorization) for the cartridge. They RTS the package and never even looked at the defective cartridge. Now I am out another $200 plus to replace the defective cartridge. Not to mention in the whole process, they do not return phone calls and they take over 48 hours to respond to emails. I do not recommend bluedoging!
