Very fast delivery.. Not tested yet

not tested... but it seems ok...

Excelente producto, llego antes de lo esperado usando el método de envío México Direct Mail. Lo probé usando unas bocinas que ya no servían y se escucha muy bien a pesar de que las bocinas son sencillas. Es increíble que con solo el voltaje de un USB (computadora, cargador o powerbank) se escuche tan alto para el tamaño del chip. Recomendado 100%!!!!

Miniaturní. Při koupi 5ti kusů je cena naprostobezkonkurenční. Jen je třeba vyřešit napájení, to v případě zařízení které obsahuje 9V baterii. USB napájení problem není. Jen je škoda, že byly pouze 4. Prostě se při kompletaci spletli. Nevadí. Za ty peníze bych to stejně nepostavil :-)

chegou com 20 dias aqui na minha residência no Maranhão, só teve um problema, uma plaquinha não presta, tá aí a foto dela, ela veio com um bichinho quebrado, mais tirando isso tá tudo ótimo

Неплохой усилитель, попробовал запитать даже от кроны 9в, работает, не сгорела)))

I am very new to audio amplifiers, but this one was really easy to hook up and make work. The pins are clearly labelled, so that really helped. I love how compact it is. I hooked up a powered mic (battery powered) to the left input, attached a 4-ohm speaker directly to the left output, and it worked. Not a huge amplification, but the mic I was using was not very strong. Overall great product. Performed as expected.
