They tune on stage, with background noise, perfectly.

not sensitive to background noise

The only thing is if there is too much background noise, it won't work very accurately.

It works well even if there is some background noise and tunes accurately every time

It works EXACTLY as it says it does

Did exactly as i hoped it would and worked exactly as it said it would

Works as it is meant too

Works exactly as you would expect

And, when I held the tuning fork against the Snark, it immediately showed a pure "A".

Highly Recommended A+++++

Too bad as I like these things.

The greatest I've ever used.

and it never seems to be quite as accurate as I like

If I miss the low E, might over tighten the string.

The Snark SN-8 works great, even though it sometime misreads the high E as an A if plucked too softly

My only complaint is that it has trouble picking up the low E during tuning
