Giving credit where credit is due. Had problems with Pro version, contacted author, very professional. Had resolved in less than 12 hours. How's that for dedication to your creation. Very informative for any level electrical reference and calculation.

Thanks for being helpful after the sale.

Not exact what I expected it to be

I bought this program to use for my Electronics classes. Found that this program tends to round to the nearest whole number versus giving exact calculations. E.g. What should be displayed 0.81 Watts turns to 1 Watts as the answer. I guess if used in real world settings this program would be useful.

Outstanding!

This app has been a huge help, and will continue to be an invaluable reference for me. I've used it extensively during my Electrical and Instrumentation apprenticeship.
