- Reviewed in the United States on February 23, 2026Color: yellowVerified PurchaseSo 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.
- Reviewed in the United States on October 31, 2025Color: blackVerified PurchaseAfter 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.
- Reviewed in the United States on February 10, 2026Color: yellowVerified PurchaseIt'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.
- Reviewed in the United States on February 20, 2026Color: blackVerified PurchaseWorks and fine , good quality product. Sounds nice and loud
- Reviewed in the United States on January 18, 2026Color: blackVerified PurchaseI bought two, one unit has noticeable strong hiss noise from speaker, no matter in Metronome or tuner mode, no matter what speaker volume I set. Also, tuner is not accuracy, it is about 1 key lower below 2C for both units I bought. If you use if for violin tuning, you cannot tune G string with this one.
- Reviewed in the United States on January 5, 2026Color: yellowVerified PurchaseGood metronome with lots of options. Battery lasts long.
- Reviewed in the United States on November 12, 2025Color: blackVerified PurchaseThe 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.
- Reviewed in the United States on February 26, 2026Color: blackVerified PurchaseDidn't work for me. Tuner didn't pick up sound too well for a trumpet.

José FernandezReviewed in France on August 22, 20255.0 out of 5 stars pas compliqué à utiliser
En tant que débutant à la guitare, j’avais besoin d’un accordeur simple, et celui-ci fait bien plus que ça. Il accorde vite et bien, mais aussi sert de métronome.
L’écran est clair, l’appareil tient bien dans la main et il n’est pas compliqué à utiliser. Pour le prix c’est vraiment pratique.
