I use this tuner mainly for tuning my electro-acoustic guitar, it is very simple to use and works very well. I have never had any trouble with the tuner picking up the sound of my guitar and you can simple place it on the side and go through playing each string. The little diplay tells you if the string is out with a useful needle say which way you need to tune the string. When it is finally tuned it will sound out a beep to tell you the string is done and in tune, then you simply move onto the necxt untill your are finished. There are to be honest a quite large number of features included with this tuner such as a metronome and ability to change what pitch and tuning you want to adhere to. This for me, was besides the way, and in all honesty I haven't used any of the features apart from the simple tuner itself. So for this use alone it is a worthy gadget and makes life a lot easier and for lazy people like myself lets a machine do what I can't be bothered to do myself. The battery life is also astonishing I have had this tuner for around 3-4 years and it is still on its first set of batteries.
