Tuning accuracy is better than any non-strobe I've used, and it's actually easier to use than the 'real' strobe tuners that I've used, because you can hold the light over the 12th fret and easily see the fundamental, rather than have to fight with pickup position sensing overtones. The lights flash at 1/2 the frequency of the silver (guitar) one, but it still works well enough that I don't need any other tuner.
