not sure how to rate it yet. It's SMALL!!! Get a magnifing glass and spot light. Not only to see it and the screen but, the directions printed in black on the brown packing. Still can't figure out how to work it. Pretty sure it's a powerful tool, once it works for you. Doesn't beep and not as huge as as Snarling Dogs piece. Glad I got both. Now, how to read & use this thing???!!! Rated it AVG. only because I had to to get my review in. Still unsure!!!!!!!!!

This is a great little machine for the money. The screen is small and the graphics are small so put on your reading glasses to use it but it is so handy and portable with a wide variety of features for such a little thing. A great way to put a lot of information in your pocket. I love it!

This product should have never been sold to the public, it is practically impossible to see anything on that tiny screen and to make matters worse the resolution of the screen is the worst I

I have been playing guitar for a couple of years and wanted to learn some keys. I read a couple of books by some pros who recommeded this gizmo. I thought "How good can it be for this price," but I bought it anyway. A good little machine for sure. Small, very handy, works great. I would pay twice as much for it. Great for chord playing on the piano.

Well, it beats lugging around a thick chord book! It's tiny as well, so keep an eye on it otherwise you could be looking for it all day. A very useful little gizmo, easy to use with a clear, if small display, it contains data for around 2000 chords and the variations. Also has a nice little "find" feature, you program the notes and it tells you the chord. Again, a very handy little gadget to have and easy to use.
