D'AddarioNexxus 360 Rechargeable Guitar Tuner - Clip On Guitar Tuner - Acoustic Guitar Tuner - Electric Guitar Tuner - 24 Hours of Tuning Time per Charge - Rotates 360-degrees

Tiny with a really nice and bright display, and the rechargeable battery is great. I use it on my classical guitars, the clip is just barely wide enough for the thicker headstock but it fits and it stays in position. I've only used it in standard tuning so far but it picks up all the strings very easily and seems accurate. Swivels in any direction so you always have a good view of it. Great value for money.

Accurate enough for a clip on with a very readable and adjustable display. Good battery life. Does pretty well with lower tunings (better than a fender clip on I have). A good affordable option if you need to tune up quick, but of course won't compare to something like a tuner pedal (especially a strobe).

I have several other clip on tuners and I always have to buy batteries for them . Well enough of that . This tuner is fast, accurate and compact and rechargeable which is awesome !! I use drop tunings for the material I write and play and this tuner calibrates and remembers your last setting . This tuner is extremely well built . I can't say enough about how impressed I am with it's performance . Bright screen as well !! 5 stars easily !!!

Works pretty good on guitars. Battery life is great. Doesn’t do the best job on bass guitars I’ve noticed.

great accuracy, visibility, and ease of use. the hinge and swivel make it so i can always turn the face to be able to see it upright and head on no matter where i need to clip it on the headstock. the display is crisp and bright. the main reason i got it was for the rechargeable battery because i was tired of buying batteries for my snarks but i’ve had this over a year and the battery is still green!

Nifty little gadget - it works very well: it holds its charge very well, is flexible enough to make viewing it while tuning the guitar easy, and its clamp, for such a small tuner opens up wide so it should be able to grab on to most guitars.It is rather small....I lost my first one somehow, but bought another to replace it and am doing my best not to lose this one.

Excellent product. I really like the fact it is rechargeable. I have several of these devices, each with CR 2032 batteries which they eat like I do slices of sourdough bread. This unit articulates in just about every conceivable position making it fit anywhere. It was very easy to set to 440 hz or whatever you choose.

Works great in live performance, high noise, low lighting environment. Very small, barely noticeable;
