The two most useful music utilities in one pocket sized package. Large multi color display easy to see and read. Rubberized buttons allow tactile feedback and easy access to multiple modes and features. This has earned a permanent place on music room desk...will not be living in a drawer. If you dont look at what Donner has to offer, you'd be making a mistake. Truly our new favorite music company.

    So far I'm extremely satisfied. The battery lasts months on a single charge.
    Easy to switch between modes, controls are simple to understand for both the tuner and metronome modes.
    I really appreciate that you can change the tuning frequency to other than A = 440Hz. My initial use for this was a gradual pitch raise on a 100+ year old piano. Made it much easier to do "in-between" steps. Would definitely recommend.

    After considering a few different metronome/tuner options, I settled on this product and made the purchase. It functions really well and compared to other tuners it seems to be very accurate. It is an excellent product for the money BUT sound quality is a bit lacking. By that I'm mostly referring to how loud it is at full volume, although it is a tiny bit louder than some others I have tried it still falls a bit short. Other than that it's GREAT. The screen is clear and easily readable as well and I would recommend this item to anyone looking for an all in one option.

    It's a cute little device and seems well made, but nowhere does it tell you how to turn it on and off. It took me a while to realize there's a big button on the front which is mentioned only in its use for Training mode, we are not told that also serves an on-off switch. So I put on my face mask and safety glasses, took a deep breath, and Lo! I got a display.

    I got this mainly for trainer mode. There are no instructions as to how to get into trainer mode. I eventually found, by trial and error, that holding the Mode button in for a while gets you into it. The purpose of this mode is to tell you when your playing is synchronized to the metronome beat. It does work, but I have two criticisms: (1) The metronome is silent when you are in this mode, so you have to look at the red lights to see the beat; I wish you could have the metronome sounding in this mode. (2) I wish the display would say whether you are jumping the beat or lagging the beat. But the training light just goes on and off, depending whether you are on or off beat.

    The product title states that this is a "tone generator tuner," which doesn't actually make much sense, but I assumed this would have a "tone generator" function. It does not. When I reached out to Donner to ask about this, they gave me what was clearly an AI-generated response about how to enable the tone generator function and included a picture of a page from the manual that came with the tuner. The image of page they included (which correctly stated how to use the tuner function, but not a tone generator function) contradicted the instructions in the email. When I responded that that was not helpful, they replied stating that they had "taken note of your question and have forwarded it to the relevant department for further investigation and analysis. We will contact you as soon as possible with more detailed and accurate information.We expect to receive feedback within 2 to 3 business days. As soon as we have any updates, we will contact you immediately." That was over a week ago and I do not expect a response. Although the tuner and metronome functions seem to work well, I would give this 0 stars if I could for the misrepresentation of the product title and the completely useless "help" they offered. I will be returning this tuner.
