  17. b***b

  18. AliExpress Shopper

    Достатка IML как всегда на высоте. Всё работает, не ожидал что он такой маленький. Спасибо продавцу.

  19. 0***J

  20. A***n

    Product is good. but the left port to connect speaker is not working.
    I was also charged additional Ghc14 at the post before I received my item. Overall it’s a good product

  32. M***y

    Товаром задоволений, ще не провіряв. Прийшло швидше вказаних дат. Запаковано надійно. З продавцем не спілкувався. Єдиний мінус не має проводка до мережі. Купляв окремо на радіоринку перехідник з 220 на 12 вольт.

  33. M***c

    Quick reviev with teardown:

    Audio amplifier IC is CD7266CZ, so you can expect only 2x7W and not 2x20W as seller advertises!

    Bluetooth/FM IC is some unknovn with label AP28581. Radio reception is great, overall sound quality is solid, but don’t expect too much for this price.

  79. g***a

    Columns from the old Panas 6 ohm, pulls plays on the middle very cool! Radio Mono and this is the only minus. and so played all day and barely warm, shorter I’m very pleased!!!

  80. D***n

    Very quickly delivered. In two days. I haven’t checked yet. Power supply included no

  81. M***s

    Very happy with the power and sound quality, for the price you have is very good

  82. AliExpress Shopper

    Excellent and very fast

  83. A***v

    Unexpectedly very good product.
    Connected two speakers from the old Thompson radio, the volume of sound at the maximum is very decent-you can fire. At the same time I use the power supply for 1A total.
    The radio is clear. With line input, the volume level is both from Bluetooth, lower than with USB and radio.
    The volume on the remote is additional to the volume on the panel, not duplicated. If you put the maximum on the panel, you can still add the volume from the console.
    I wanted to flip the board inside, so that the fasteners were on top of the case-so it will not work without a little improvement. Inside the case there is a guide for the board, also on the side two screws hold the radiator cooling of the transistor. When turning over, the board will hang out, and there will be holes from the screws.

  84. E***v

    It came quickly, 3 weeks DPD in Citilink

  85. F***o

    me llegó bien, rápido y suena lindo

  86. e***a

    The buttons on the remote are slightly gnawed. The power does not go in the kit.

  87. AliExpress Shopper

    Item is as described, power is sufficient for the price
