Not better than previous tuners from Snark
Reviewed in the United States on July 10, 2016
Maybe I got a bad one, but the 1st, E string (the high one), on both of my guitars shows up as A in this tuner, unless I put my hand on all of the remaining 5 strings; and, then, it usually shows an E, but not right away. This quirk just doesn't give me a "warm fuzzy" so I've reverted using the built-in tuner on my acoustic. (Honestly, this is not a step up from my old SN-1, which still works fine, though it lost one of the rubber pads.)
Update (05 Aug 2016): I had contacted Snark support about the problem I was seeing and they said it was not normal, and sent me a new tuner. This one seems fine, but it is also clear (and confirmed by Snark) that they have changed this model slightly. The older one that I got says SuperTight on the face and has a metallic brass/gold power button and bars for LEDs in the note display. The newer one simply says Snark on the face (both say SuperTight on the back), has a yellow power button, and small square LEDs to comprise the note's letter.
Picture of the two models attached while displaying the odd, occasional confusion about the high-E tuning. (The older display is really just as clear as the new one, but the angle I turned the guitar/camera to cut out reflected overhead light makes it seem grayed out a bit.)
Update 2 (21 Aug 2016): I've had a chance to use the newer version tuner in noisy situations and it definitely behaves better than the older model I was originally shipped. I didn't A/B it with my old, blue Snark, but it behaves well enough that I can say it seems to be Ok for my purposes. It does not seem like an improvement, though, so just moving the review from 3 to 4 stars.
