Donner Metronome Tuner for All Instruments - Guitar, Bass, Violin, Ukulele, Trumpet, Chromatic, Clarinet, Flute, 3 in 1 Digital Metronome with Tuner/Metronome/Tone Generator, DMT-01

Has a nice big cool blue screen, it's easy to see on my pedal board. I use it with an A/B switch so it stays isolated. It tuned my guitar very accurately, can't say that about other tuners I used. The metronome sounds like a pong game but is very easy to use and useful for practicing. It's a little tricky to use at first but once you get use to it, it's easy. The price is great for what you get. You can't go wrong with this purchase.

Seems to work well on guitar and piano

This is inexpensive and does what it’s supposed to do. I found the buttons and user interface confusing, though.

I use these to tune electric guitar and bass, and I appreciate that I can just connect a 1/4" cable right into the tuner. The metronome is a neat bonus.

Good Donner Metronome .working is very good my child like it

Well there are a few thing about this tuner that were pros and cons. First and for most. It's cheap in price, and comes with a clip-on little mic, so its nice. Now, my biggest complaint is that is about 5-10 cent out of tune, compared to my other tuners (a lot more expensive reliable tuners). My other complaint is that it doesn't really pick up the lower frequencies, I had a little bit of trouble tuning an upright, jazz bass and it would pick up the keys on the piano from B3 down. But other than that. It might be a nice guitar tuner looks awesome, with all the colors too.

I bought this item because I was looking for an economical and easy to use metronome to use with my five string banjo. I got that with this item plus it also has a pretty reliable tuner as well. The metronome and tuner have lots of useful settings/functions and is compact enough to fit in your pocket. Includes everything you need to get started.

More than you're paying for. I haven't dropped it, so time will tell how stable it is. It's very light, and a cable can pull it off a table, so I leave mine in the other hazard area - the floor. An improvement would be making it feed thru and designing the riser to also function as a belt or strap clip.
