It works great. It also shuts itself off when not in use. Big help!

Inexpensive and accurate.

Works as intended. I'm a total beginner with the guitar but it displays the note clearly and seems easy enough to use.

Works good and looks great.

I would recommend this item!

It works great at a great price. My other tube is a Korg and this one is just as good. Easy to use and view.

Full-featured, secure and well-padded clip, excellent multi-color display, responsive. Nice touch that it came with a battery. Would recommend without reservation.

Works great, so easy to use, allows you to tune all the usual stringed instruments. I can't recommend it highly enough! I wouldn't be without it!

Not easy to use. Settings are complicated and if you accidentally end up in the wrong frequency you’ll be tuning the guitar to a different scale.

I figured for the money it was worth a roll of the dice but I came up craps. Evidently these work for some people but I can rarely get mine to register a note at all and even then I have to literally bang on the guitar for the tuner to sense anything. it's literally useless relative to the purpose for which it is intended.

They say you get what you pay for but in this case I didn't even get a tuner, it's just a hunk of plastic that looks like one.
