My local shop doesn't charge much to press headsetBBs in, but this lets me do it on my time. And I used to workmanage bike shops, so I know what I'm doing.
Five stars for performance and build quality generally, three stars for value. Averages out to four stars. If you are a pro mechanic pressing lots of bearings, then this seems like what you need.
A must have for guys who like to build their own bikes. A quality and easy to use tool that will last a lifetime. However, a bit pricey for a tool that isn't used a lot.
