There are two things I don't like about it.
1: It's only single output, IMO a bench supply should be dual output as=20
many analog circuits need both positive and negative supplies
2: It doesn't have binding posts. I want to be able to stick bare wires=20
on my PSU directly without having to worry about fitting connectors first.

For a general lab power supply i'd much rather have dual outputs and=20
binding posts than programability and super accurate output voltages.
