The screen size is perfect and this read my notes better than my other tuner. Simple set up as you just connect the meter to the sensor and clip to the guitar. or you can use the built in Mic to trigger the tuning. the metranom was interesting to say the least with many many settings of rythems and speeds to work from. the display is bright and easy to see has an animated Metranome so its not just sound. Its light weight takes 2 tripple A batteries. all in all im enjoying it so far this wil lcome in handy when my neighbor crys tune this. If anything changes i will update this post till than have a great day.
