Based on other reviews I really had high hopes for this tuner. However, the tuning is not nearly as tight as other tuners I've used. But the bigger problem leading to submitting a negative review is the fact that one of the three prongs on the back of the tuner head which cradles the tuner stem and allows it to pivot broke within a few weeks, just past the allowed return date. I may be able to crazy glue it to the stem but honestly I don't think I'll waste my time. The quality of tuner just isn't worth it.
