Purchased the product around Jan 2012 The unit is fairly light in weight, so you need to make sure it is resting on a hard surface otherwise unit will wobble when printing.
Setup was long, but self explanatory, wireless connection took a while, could not pick up the signal a few times, so connected it through USB first then tried Wireless, and it was fine. Could be to do with my wireless router.
The noise during printing was not loud as I expected it to be with a light weight machine, so pleasantly surprised. However during printing, it spits out the printed documents, like it's disgusted with it, and sometimes tries to chew the paper back in, so if you are not careful and watching it, it can mess up your printing. With this in mind, may not be suitable in an office environment. It would definitely help if there is a separate tray entirely for paper that is printed, just like they have with the top paper loader, so HP take note.
Scanning and faxing is marvelous, works a treat, and very happy with the results so far
With the price I paid for it, which was cheap, I would say overall is definitely worth it.... I just hope it will last for many years.....here's hoping :-)
