I've used my original Snark for several years and bought this one as an extra. This on certainly works easily and accurately, and it comes with a battery so you're ready to go right out of the box. But there are two things to be wary of: first,it states right on the box that it is not to be used with ANY Gibson guitar,or other brands with certain finishes. Now I don't play Gibson so that doesn't apply, but I don't know whether the finish on my instrument is equally vulnerable. This will require a work-around (shims between the tuner and the guitar maybe?) or at least some research. And second, this tuner only works with vibration and must be clipped on the instrument; it will not register sound through the air the way my old Snark does and I wouldn't have bought it had I known that. But if you can live with these two issues it's worth the money.
