What is your opinion of this product?
I wanted a strobe tuner because I do setups for friends, the price was right. Some LCD strobe tuners are 'laggy' or virtually unreadable, not so with this unit.
Dead-on drop tuning, key changes, A440 reference adjustable from A400 to A490, has a 'sweet' tuning option for guitar, reads correctly. I tune my Strat in Eb, and it shows Eb, other tuners say D#.
if the display moves to the right, your note is sharp, to the left, its flat, and frozen is in tune. Comes in a metal tin with rubberized foam to protect it. The main shell is metal, not plastic, however the clip and pivot ARE plastic, and should be handled more carefully.
