Ordered HP97 cartridges, they sent HP99. Unit would not accept it. They refused to accept returns on the open, (but unused) unit. Am thoroughly disgusted with their attitude and return policy Its obvious they are extremely hungry and desperate for any cash they can get their hands on. Since they obviously need the money a lot more then I do, I donated the entire $30 to their bankruptcy. Hopefully they will choke on it! Don't make the same mistake I did and waste your time and money buying from them. Pay bit more and deal with a reputable company!
