So small so light weight yet you can see the LED no problem, this is very easy to use and very accurate it really doesn’t take a well-trained musician to figure this one out but after you are done using it you will sound more like a well-trained musician. I love how easy the battery is to change very simple you don’t need a scalpel. This will keep you in tune and sounding great, I have used others in the past and liked them but always had to go look up what all the other reading meant this one is SIMPLE it has a 360 turn so you can just clip it and adjust with out having to remove it every time you change your position. You can really use with just about any string instrument and it is very sturdy. Great price A+ to the makers of this item!
