This violin metronome from the KLIQ brand is an excellent pocket-size unit. It runs on lithium polymer batteries, which charge very quickly. The metronome weighs about 6 ounces. What’s more, the display is excellent.
As far accuracy is concerned, it doesn’t let down at that front. It is a 3-in-1 unique device. If you want to use it as just a metronome, all you need to do is press the mode button.
