I like the size and functionality of this computer. The ability to do wind calculations and still stick it in a shirt pocket was a great selling point.
I am a little disappointed in the quality on the calculator side. The lines on the inner and outer scale do not align when the rate arrow is set to 60 on the outer scale. Some of the lines are correct and some are off as much as a line width. I don't think this is enough to significantly affect the calculations, but it would be nice if it were right on the mark.
