That's the one I recently purchased (well I got just the rfid version)
It works, the software is a little clunky - maybe because I networked installed it rather than on a standalone PC, which required a firebird sql install to make it work iirc (which I managed to do - with not knowing anything about firebird or sql, so it couldn't have been difficult

)
At the end of the day, you are looking at budget systems, as I was, so it's not going to be all singing and dancing but it is functional.
Can't say it's saved me any time processing the payroll though....probably with all the missed & incorrect clocking it probably takes me longer than when we just used time sheets

(we do have a very variable workforce though, with only half on standard hours)
