"So far, I can tell you that it has cut time to a fraction of what it has taken in the past... no more soldering, no more having to take various measurements and then calculate for correct values.

Basically, I have no dislikes at all. A back-light for the display would be nice but I understand why it's not there and that is very minor.

I especially like the idea of no power switch and the auto on/off. Too many other pieces of equipment I use daily (cable testers, cable tracers, radios, etc.) have external power switches and it never fails that somehow they are left on or get bumped on in their cases. The auto switch function between voltage/current measurement and output wattage measurement is nice too. Having no front panel controls at all, unlike the other meters I have used, makes Compu-Bias easier to use. It also makes it easier to store since you do not have to worry about control knobs sticking out and running the risk of breaking them."
