I've used this and found it pretty cool. They still have a lot of enhancements that could be done to the product but it's a real efficient way to pound through lists. Just upload a spreadsheet and listen to hold music while connections are made. Screen pops let you know who you are talking with.

They really need to start integrating it with the major CRMs but it is still valuable in its early form.
