Ease of Use

I ordered this on 6/24 and received it on 6/27 via standard mail. So the shipping was free. I was expecting it to take a week or more. It was easy to set up and seems to be a good product. I woud certainly recommend it

HP 640 Fax

on 7/15/2008

This product is somewhat deceiving. I wanted this to use in my home office and it appeared to have a speakerphone but in reality is only a loudspeaker. I use this for meetings and really wanted a speaker phone. This is my only complaint about the unit, otherwise it works well and is easy to use. I've used the fax and that works well also. The standard shipping was very fast, got it long before I expected it.
