As advertised
Works good. Smaller than I expected.

Great value
Great value for the price. Has all the basic features you might need, like volume control, and earbud output. Maybe not quite as easy to change the settings as the DB 90, and you can’t pick different tick sounds, but works perfectly well for a small metronome, portable, great for beginners or intermediate.

Great features, good size, but eats batteries
This is the best pocket-sized metronome I have owned. The only downside is it requires a new battery fairly quickly. But aside from that it is feature-rich and a useful addition to my tools.

Acceptable Battery Life
Some reviews that I read before buying the DB-30 questioned longevity of the battery. Today is my first battery change after two and a half months of daily usage. The battery didn't die, per se; the metronome just started responding oddly to some input. A new battery fixed that. Longer battery life is always a plus, but I am fully satisfied with that of the DB-30. I also like the metronome very much because of its size, ease of use and overall quality.

This one is my favorite from now on
I have tried different metronomes before, but none of them as convenient as this one. Traditional is fragile and bulky, digital gave me terribly sharp and loud, disturbing sound, I did not like metronomes until I got this one, now I am happy to exercise using this metronome, it is so light, handy, does not take much place, easy to use, gives very soft and easy adjustable sound, so people in next room are not disturbed with my workouts and it is pretty advanced device, it gives different rhythmic patterns, it uses lights indicating strong beat and arrow on monitor, so it may be used even without sound, good range of tempos, can be used as tuner ant has more functions, which I do not even use. It has small size, so it can be always with me and I really love this metronome.

Great value - will work for pretty much any temp you would need.
Maybe not as fancy as some of the others but a great value and does what you need it to do. I would say it will match any tempo, count etc. you would need. very easy to adjust, adjustable volume & pause buttons are handy. easy to use & simple to adjust beat per minute. Definitely recommend.

Horrible when used with headphones
This is an entirely competent metronome. You can easily adjust the tempo, change how many beats, which beats are sounded, and choose more complex rhythm combinations(e.g., 6-7, or 4-3 time). That's all good, and it's really easy to do. It also has a rotary volume control and it can get about as loud as my cell phone's low battery warning. It only emits one sound, an uninspiring chirp which is slightly higher in tone on the first beat of the measure. It sounds like you flashed back to the 80s and someone is playing pong. Some people might find it annoying, but you'll probably get used to it. There's a handy clip on the back. It will also play continuous computerish reference tones at different note values, if that's of use to you. Finally, the very useful display makes all the functions pretty intuitive and has a good pendulum and flashing LEDs that help visualize the tempo. There is also a mini stereo jack for use with standard headphones. That's where it's horrible. When using the built-in speaker, the volume control is gradual, as expected. When using the headphone jack the volume control isn't gradual - it really jumps up extremely quickly. Without headphones, you'd probably have the volume around 70% or so. However, with the headphones in, anything below 10% isn't really audible and anything above around 15% will be like an ice pick piercing your ear. So, if you go between built-in speaker and headphones (I do, depending on the time of day), you will eventually blow your ears out with this when you forget to turn it down. To make matters worse, sure you can find that sweet headphone volume spot of between 10-15%, but the sound through the jack is absolutely horrible and distorted. What is a pure chirp from the built-in speaker is pretty muddled/distorted in headphones. What a waste that Boss went cheap and careless on that function. I use this for drumming, so that may explain my use scenarios. If you don't use this with headphones, you will probably be very satisfied and it's a good value in its price range. However, because the headphone volume problem is significant, I docked it two stars since it's a one star product in that regard.

Best digital metronome there is
I had bought one 12 years ago and I’ve used it everyday until I had to change to a new one this year. Very rigid, and durable. Absolute perfection on the technical side. Now once I got a new one, I know I’m sorted for at least a decade!

Çok işlevsel
Gayet güzel bir metronom. 1 saat sonra kendisi duruyor. Dinlenmek için iyi bir özellik. Çok farklı ritimleri ayarlamak da cabası. Dikkat edilmesi gereken şey, kullanım kılavuzunda da yazdığı üzere, bir anda durarak 120 bpm’de sabitleniyorsa pilinin değiştirilmesi gerekiyor demektir.

秘密にしたい位、最高の贅沢でした。
もう、兎に角、 5拍子7拍子9拍子のトレーニングが 出来るので最強です。 購入後は嬉し過ぎて嵌りました。 そして、その事で大変でした。 それ位好きに成りました。
