Why you need a RC Watt meter.

Just wanted to let you know I LOVE this meter! I'm playing around building CD ROM motors and the meter makes it so easy to objectively evaluate the performance of each motor. I am also very pleased with the size, construction and ease of use.

Thanks for a great product! - T.S.
