This is a FANTASTIC tuner, attached to the WORST mount I've ever had. Within a week of buying it, the plastic attachment point on the back of the tuner broke off entirely, leaving me unable to use this tuner for anything.

Before it broke it was phenomenal. Pretty much usable for any instrument I owned. I tried it on my soprano uke, my 6 string uke, my 7 string electric guitar, my 6 string electric bass, a recorder, and it had no problems detecting pitch. The screen is easy to read at a glance, and the microphone/vibration switch is very convenient when tuning something you cant directly clip onto. I never had to use the extra features, and now do not have the ability to.

The mounting clip is easy to use and holds this tuner VERY securely, I was never worried about it falling off or moving while using it. Unfortunately I wasn't able to use it for very long. While adjusting the tuner's face about a week into owning it, I noticed that it was becoming very loose. Within a day or two it would wiggle and move until eventually it broke off entirely. I don't know if this is a common defect, but for this reason I do not recommend this particular tuner. I'd like to see the same tuner with mounts that aren't made from plastic, and would gladly pay to mount this excellent tuner to higher quality materials.

It really couldn't get simpler. Clip on, and press the button when you want to tube. For me, this is great because I used to bring a tuner pedal... and then hey, as long as I have a tuner pedal, I might as well throw in a delay pedal as well, since I can split the power. Well, you know what goes well with a delay pedal is a little overdrive... and maybe some chorus... and then all of the sudden I've got more pedals than songs. With this, I really can bring just my guitar, amp, and clip-on tuner. Love the simplicity, and it locks onto the note fast, too.

I received one (left in picture below) on 12/12. It was finally used at class for the first time this past week. A piece that holds the turner together broke making the turner unuseable. So I ordered another one (paying for it as no return policy) thinking it was just a faulty one. Received second one today and went to use it and the same piece broke on this one (right in picture below).
Thinking now there might a design flaw on these?!?!

DO NOT GET THE ST-8HZ RIGHT NOW! THEY ARE MESSED UP AND YOU WILL BREAK THE THING AS SOON AS YOU ADJUST IT!

I have been through TWO of these things so far and they initially arrive fine until I turn the tuner a little bit, then suddenly one of the three plastic pieces breaks off on the tuner part (not the clip) and the tuner is completely useless. I've emailed Snark and haven't received a response back. There Is a manufacturing defect with these things.

The 3 plastic tabs holding the ball joint on the back of the tuner are so weak that you can nudge them and they'll snap right off. There is a manufacturing defect with the batch Amazon has right now or something. I don't know. Do not get these from Amazon. Buy them somewhere else. This is as of 12/28/17 so whatever batch they have is garbage.

This is my third Snark, and the first with this Hertz tuning which I haven't even used. I didn't realize it was going to be as big a deal as it is. You can't just tune individual strings with the Hertz tuning. You have to tune them all each time, in sequence.

I'm not crazy about the larger bars on this model, and it doesn't seem to be as accurate as my older models. At least it doesn't feel that way.

Last but not least, the attachment point on the rear of the tuner for the ball on the arm of the clip has already broken. There are three phalanges, just like the older models, but with one broken, the arm of the clip cannot be held in place. This renders the tuner useless, as it is contact only and that contact is via the clip and arm.

Update, 9-19-17: Adding two stars back for the great customer service, as Snark quickly replaced the broken item. Still like the older ST-2 better, but a Snark is a Snark.
