I use it for several months.
I can not do without the headphones: volume low enough in the ears, the sound is soft - unlike some metronomes strident.
The display and the LEDs are good guides. Little more enjoyable: tap tempo function.
Very convenient, small, flat, one can hang from his belt with clip.
Wide range of rhythmic patterns / actions.
I found it at 22 euros, an excellent quality / price ratio: the choice I would do without hesitation.
