I bought this tuner,more out of curiosity than anything else,as i wasn't sure if it would work with my flute,but it's cheap enough to take the risk.The only drawback with it in my view,is that it could do with a flexible arm on it,as when it's clipped to the flute,unless you have eyes on the side of your head like a horse,the screen is difficult to see.The fact that it lights up green when it is in tune does help in this respect,but it's still a bit awkward.I've checked the tuning with my trusty microphone type tuner,and it's spot on.If you are a player of an instrument where you can see the screen more easily,this is well worth buying,as using microphone based tuners in noisy places is a nightmare.
