I called GnG IT Specialist to diagnose and repair my HP printer which suffered from chronic paper jams. I made arrangements with Wllton Guerrero who sent his brother, Pedro Guerrero, to my Bronx home the next day. He dissembled parts of the printer, diagnosed the problem, made the repair in a short time for a very reasonable price. Pedro was efficient, pleasant, and willing to explain the process to a senior citizen who is new to computer technology. He also arrived within the promised time frame. I highly recommend them.
