This is my second set of PCBites, bought mainly because I needed more probes, although other parts would be nice to have too. These probes are the best after cutting bread in the fine pitch surface mount world. We used to be able to attach adapters to DIP components and measure when the ground cools, but not anymore. PC Bits make it as easy as there aren't enough full-fledged, expensive mic positioners to sonic your board. These sets are just great.
