Update 9/22/2017
I did some testing with a high accuracy frequency source generating a sine wave and found the resolution to be about 5-6 cents. In other words, your tuning could be out by 4 cents and this tuner will still indicate you are in tune. This is fine for casual practice, but if you are doing studio/recording work you will likely want your tuning to better than 2 cents. I only have one unit to test, so your results may be different.

----------- Original review
This is a basic tuner that works by vibration only (it doesn't have a microphone), nor does it have any extra features such as a metronome. It came with a CR2032 battery and a minimal instruction sheet in English and Chinese. I already have a Snark ST-2 which I like a lot, but figured I would try a less expensive option for a spare guitar that I leave in another room.

The accuracy seemed good. I tried it on a couple of electric guitars and it matched the snark for the most part, however the snark seemed to have slightly better resolution (this tuner would indicate the string was in tune over a wider range than the snark). It's very easy to operate, just depress the button on the side for about a second and it comes on and is ready to go. The display is bright and easy to read and turns green when the note is in tune. The illumination is bit uneven being brighter near the top, no big deal. It automatically shuts off after 2.5 minutes, or can be manually shut off by pressing the button until the display goes dark. Responsiveness is reasonable, the snark is slightly faster, but I had no trouble using this one.

The instructions indicate it is adjustable: an A4 note of 430-450hz, HOWEVER I didn't figure out how to change it from anything other than a standard 440 A. In playing with it, I did discover it has different instrument modes.

Across the bottom right of the screen, there are letters to indicate the mode: c, g, b, v, u. I'm guessing that c = chromatic/generic, g = guitar, b = bass, v = violin, u = ukulele. For stringed instruments, it displays the string number when plucked. If the mode is set wrong, one or more strings will be incorrectly identified. To cycle through the modes, tap the button quickly after the unit is powered on. It would have been nice if this information was in the instructions.

The construction is not as sturdy as the snark and it wouldn't handle drops as well, but at half the price there is bound to be some compromises. For a quick tune ups, this fits the bill. For those that require very high accuracy or a very sturdy design, more expensive options may be justified such as a pedal chromatic tuner.

I hope you found this review helpful.

Love this! I am an artist who makes Gourd guitars and Ukuleles. I am not a great musician so tuning the instruments for shows was a nightmare. With this handy gizmo - I can have the instruments in tune and ready for a passing musician to become a buyer.

This tuner is very nice! Features a large easy to read backlight display and uses chromatic, guitar, bass, violin, ukulele all user defined settings. The only complaint I have is the inability to change the tuning frequency. It is always 440! Sometimes I prefer to tune down to 432 so I have to use a different tuner. If you are always tuning to 440 it's great! Small enough to throw in your gig bag or case while on the go. The tuner is all plastic, fit and finish is decent.

Product came on time and is as described. My brother recommended I order one of these for my ukulele but I can also use it on my violin. It just clips to the top of either. It has an on/off switch. Works perfect and is not too big so fits in the case with the instrument without having to take it off but even if I had to, it just simply clips on and off like a clothes pin. Love this! Would recommend.

needs a bit clearer documentation but a few minutes and you can decipher how to use it for a novice. Also wish it flat said "E flat" because that's what i'm used to seeing on my old device since i tune to E-flat almost 100% of the time.

This tuner is really helpful. When I'm onstage I usually use a floor pedal tuner but that needs to be plugged and all set up. With this tuner you just need to clip it to your guitar and that's it. The display is really bright and very accurate. It's also a pretty great price.

Might love it if it came with some instructions...not everyone is a guitar aficionado.

My sons girlfriend uses it for her uke and guitars. She reports it doesn’t pick up the B string on her guitar that well, but otherwise works and is clear to see in both light and dark settings.

Preface: Full-time solo acoustic vocalist. Legally Blind. Easy to see, I do not wear eyewear on stage. Small so easy to keepin case. TUNING: seems to be right on and easy to use. Buying more for every case.
