I've had mine for 7 years now and it works as well today as it did when I first bought it. Have a set of 2032 cell batteries on hand and you'll be good to go. I use mine for my guitar and ukulele. It works for both.

A little while ago I thought it was broken and was about to toss it after 7 years of use but I simply removed the old battery, held down the silver button in front as I inserted the new battery. It's worked well since. Online you'll find directions that mention the up/down arrows in the back, the model I bought 7 years ago only has the silver button in front. So to reset the old model Snark SN6 (mentioned above), remove old battery, hold down silver front button while inserting new battery, upon closure of the battery compartment, release the silver button and you should be good to go.

Much easier to use than the tuner that came with my ukulele. It responds more quickly and more accurately (very repeatable). More graduation lines quickly shows me how close I am to in tune. Bright screen is easy to see, even from a distance. Because of the large size and weight that throws off the balance of my ukulele, I always take it off when I'm playing.

I am new to the ukulele. I have a Kala soprano ukulele and use this to tune it most days. I like that I can see if I am playing the right chord as I'm learning. I can shut it off, but the Snark powers off when not in use. I do notice that the Kala tuning app that's on my phone may be more accurate than the Snark -- but I can only use that if my phone is charged. The Snark is what Cynthia Lin, a YouTube ukulele teacher, recommended, so I recommend as well. *Barbara A.: Attached are photos for how to change the CR2032 3V lithium battery.

This tuner works very well not only for my daughter's ukulele and mandolin, but also for our acoustic guitars and banjo. I love the small form and accuracy, but most of all, the easy-to-see display. I don't have to strain my eyes to know to see if I need to tune higher or lower, because the red color shows for too low, yellow for too high, and green for just right (in tune). This is especially helpful when I'm trying to do alternative tuning, which I will never learn by ear. The gripper rubber has stayed on well, the clipping action has never lost its strength, and it is my favorite tuner we've had thus far for our stringed instruments tuning needs.

After having this a couple of years, it's now time to replace the battery, (CR2032 Lithium 3 volt), but after comparing the cost of a package of 4 batteries and a new tuner, I'm debating just getting another tuner and get a pack of batteries later for the one we currently have and getting more batteries later. Anyway, I love this little tuner, it's small, accurate, easy-to-see and reliable. Thanks for reading!

The Snark SN6 Tuner is so darn convenient and easy to use. Why have I used anything else? I have the usual
small box tuner for my acoustics and a pedal tuner for my electrics. This tuner works so well that I wonder why
one would want to use anything else. Well, there is one small caveat. So read on, McDuff.

This nifty little tuner fits tightly on to the headstock of my tenor and baritone ukuleles as well as my 50 year old 6-
string Kay acoustic and hefty resonator guitar. It tunes them all without busting a gut. Being a chromatic tuner
allows it to work with non-standard tunings as well. This means the tuner will read any note you play.

The tuner uses a high sensitivity piezo sensor for tuning. A vibration sensor built into the tuner device sends the
instrument vibrations to the tuning circuitry. No microphone onboard means the tuner is immune to background
noise, so you can tune your instrument in noisy environments and/or while other musicians are tuning.

-- SN6 Stats --------------------------------------------------
:: Battery Type: (1) CR2032 (3v) [Included]
:: Body Diameter: 1-5/8 inch
:: LED Readout Diameter: 1-1/4 inch
:: Weight: 0.2 ounces

There is a "˜Power Save Feature'. The tuner will dim after 5 seconds of no sound and the display will return to the
normal brightness when a note is detected. If a note is not detected for 2 minutes the tuner will shut off completely.
A nice touch.

This tuner uses two ball joints; one at the back of the LCD body and one on the clamp. This allows the LCD body
readout to be moved and swiveled around 360 degrees for your convenience. Whether you place your tuner on
top of your head stock or underneath the headstock you can still see the tuner.

NOTE 1: With regard to instrument finishes it is not recommended by Snark to leave the clip-on tuner attached
to the instrument longer than needed. The rubber pad on the bottom of the clamp could affect the finish.

Snark advises NOT to use its tuner with any instruments having these finishes: "Nitrocellulose Lacquer, French
Polish, Oil Finish, Polyurethane, or Gibson Guitars". For those types of finishes they recommend a pedal tuner
instead of a clip-on to avoid any unfortunate finish problems.

NOTE 2: The Tuner occasionally runs a "self-test" to make sure its functions are working. The self-test happens
when it is first turned on and only lasts a few seconds so don't get concerned if you see an unusual event after
you power up. It will settle down quickly.

So, I heartedly give 5 huge stars for this simple easy to use portable tuner and its storage bag. It truly is a most
flexible tuner. Why its branded as a 'Uklulele' tuner is beyond me. Focused marketing I suppose.

Historical Foot Note: The clip-on tuner was recently invented in 1995 by Mark Wilson of OnBoard Research
Corporation, which marketed it as The Intellitouch Tuner Model PT1.
