    Доставка быстрая . Пришла сильно помятая коробка , думал месиво будет внутри . Оказалось что все очень качественно упаковано . Сам модуль завернут в пупырку почти 2 метра длинной 🙂 Все целое без повреждений , полный комплект как в описании. Проверю в работе позже. SMD пайка не фонтан .Такая цена и поставлена. Выбор на Али большой – плати деньги и получишь ” с перламутровыми пуговицами…” 🙂 . Рекомендую продавца .

  53. AliExpress Shopper

    My product defective open a dispute to see if someone help me or the seller or the AliExpress
    But I’m seeing here this platform only they can out favorable they dont care with the consumer…

  54. L***a

    Haha I took my time to prove it. Gives exelent performance. Connect it with a Panasonic 3-way horn of 150 rms. In the tuitter port and a Panasonic 180 rms subboofer on the bass. I know it’s insane. But it gave exellent audio quality and exellent volume. The Bluetooth connects pretty quickly and well. It gives me nothing of lag. Having the phone relatively serca. And it hasn’t cut off the reproduction. The seller answered my questions very well and it was quite an attempt. To do something to get there but they were problems already here in Mexico.

  55. M***n

    The amplifier has arrived quickly. He has a good sound and works flawlessly. It’s all as described, only the radio has a poor quality.

    Der Verstärker ist schnell angekommen. Er hat einen guten Klang und funktioniert Einwandfrei. Es ist alles wie beschrieben, nur der Radio hat eine schlechte Qualität.

  56. V***h

    Quite a good device! Connected to the column from the old music center, Super!!! There are almost no noise, the radio does not catch very much, and with the auction it does not work, but on the Bluetooth and the linear input works Super! I haven’t tried the microphones yet. The main thing on Bluetooth works well! In principle, for me this is the main one, I’m happy!!!!!!

  57. A***n

    cok guzel paket sarmislar tesekurler
