This was the first tuner I bought when I started playing about 7 years ago. It worked great at first, but then after a short while it became extremely unreliable. The needle would act like it was possessed and switch inbetween notes, say I'm tuning e string to e...I would be at e flat and it'd jump to g something. Completely rediculous.GOOD WHILE IT LASTS, get a pedal tuner. Heavy duty, great to use during gigs
