Best little clip on tuner. If you need a tuner that is a bit bigger go for the Agthog tuner, which is also available on Amazon.

I've got several Snarks, Intellituners, a Korg standard tuner, and a ton of iPhone app tuners, but this is really my favorite. Its ability to be used on multiple instruments besides just the guitar is great. If you don't have a metronome the Agthog tuner for an additional $5 is a very nice alternative. It is bigger than this AROMA and it also can sound out the correct tone too, for old school tuning fork kind of tuning practice, as well as a magnetic ball attachment that should let the unit break apart in a way that you can just reattach it quickly. But for me I like this one a bit better as it is a bit more discreet.
One nice feature is that it shows you the string number for the instrument you are tuning, which is good for when you are just learning a new instrument. The rechargeable battery is good too, though I don't know how long the charge will last yet.
