no, Squeak, i sent it back to Goeorge Kaye, and he saw
the problem too..the 4th button, controls, wouldn't
change in low light, only very bright light--or, you had
to keep you hand over the d-beam and double-click the
control button to effect a change. the tap tempo was in and out--sometimes it was right on, other times it was much too fast or slow compared to what you tapped..that was also corroborated by Kaye.
neither was user fault or could be corrected by settings.
