AARVI Clip On Guitar Tuner for All Instruments, Acoustic/Electric Guitar, Ukulele, Bass, Violin, Banjo, Large Clear LCD Display for Guitar Tuning, Chromatic Tuner, 4 Pack Guitar Picks Included

Great for the price and works just fine. I had no problem installing the battery and tuning the guitar. It’s smaller than I thought it would but I’m happy with the purchase.

Works correctly, easy to use, tested it against a tuning fork and it's accurate.

Tuners are good, bright, and works well enough. For the price it is good. The button to turn the tuner only works sometimes, so I often have to press twice, which is fine. If you're looking for something for any other tuning than A440, this is not the tuner for you. 4 stars because the picks are so thin that I broke most of them in a few minutes.

These are inexpensive but accurate tuners. A battery was included with each tuner. The display is bright and easy to read. They are sensitive without being too sensitive. These are a great buy.

Works great my little can tune his guitar with great ease now

Good value, but not the easiest to use. Important note: to install the battery, turn the compartment cover CLOCKWISE to open, not counter-clockwise as you would expect. Turn counter-clockwise to close the cover. Once you clip it on, the screen pivots are limited, so if you’re holding your guitar in a usual playing position, you have to clip it on in front of the headstock to angle it for a right-side-up readout. The on/off button is in the back, unlike most clipon tuners, so it’s a bit awkward to find the button by “feel” once you clip it on. The tuner does work and does seem to be accurate, but just be aware of the points above.

A great value. It's incredible to think that you get two tuners (batteries included), long with some additional guitar picks that were included for $10. You simply can't go wrong. The tuners are easy to use, responsive and accurate

I bought this with high hope! Nothing super fancy which is exactly what I wanted-just a basic clip-on tuner for my guitar and my ukulele. Yay! Unfortunately, I guess you get what you pay for. It worked perfectly as soon as I put the battery in but then the first time I tried to use it, the swivel piece that holds the clip to the tuner btoke. In trying to snap it back together I realized it was only held together with a little bit of stretch adhesive! Seriously?!? So, I guess saying it "broke" is being a bit too forgiving. Very disappointing!
