Using this constantly at the front of my interface. This tuner can be set to show tuning (single note or polyphonic), even when not engaged, which can be quite useful. Good and solid build. Display is fairly bright, which I guess can be an issue in some cases, but on the other hand its bright enough that visibility in lighted areas is not an issue. Only real minus is the placement of the power supply input on the right side (should have been placed at the top), which can make orientation of an angled input jack a bit awkward sometimes.
