I found the US price mentioned attractive, but shipping, customs, and lots of red tape at both ends of the transaction made look in my own country and in Germany where prices were up close to 3 times as high. So I went with a UK eBay sale at around twice the US price including shipping.
The red model is fully chromatic (the blue one is for guitars/bass guitars only) and has two modes: vibration sensor and microphone.
My sample arrived Friday, and I only have tried it with 4 instruments so far. Microphone mode works well with a recorder, if the Snark is clamped to a stand or the like. Vibration sensing works well with my Irish type harp. It was way faster to tune the 33 strings than with an LED tuner, where one also has to check which note actually sounds. The Snark is very clear on that matter.
Also tried it with an alto trombone and with the Conn 40K. On the latter the results appear most consistent when clamped on the neck than when clamped on the bell rim.
Guitar playing reviewers tell about buying several samples.
