I guess this is one of those products that you don't you really need or want, until you happen to have it lying around. Then you wonder how you made it this far without! It's such a great little help when figuring out solo's, complicated chords etc. No more messy lines in the margin of my lead sheets. For me, the size is just right, not to big, not to small. It would be nice if it came with an ink pad or if Thomann would sell ink pads, but those can be bought elsewhere.
