Sebagai pengedar audio kecil, saya membeli amplifier AS21 ini secara berkelompok dari Creatall sejak enam bulan yang lalu! Umpan balik pelanggan semuanya positif, terutama kalangan muda sangat menyukai fungsi APP-nya—boleh ubah nama Bluetooth, ganti lagu dengan menggoncang hp, operasinya sangat moden. Dari segi kualiti suara, reka bentuk rendah hingar sangat baik, walaupun volum dinaikkan maksimum tidak ada hingar, sesuai digunakan untuk memasangkan speaker rumah atau audio pesta kecil. Waktu penghantaran syarikat sangat stabil, tidak pernah lewat, perkhidmatan pembungkusan tersuai juga profesional. Setelah dicetak logo jenama kami, pengetahuan produk meningkat banyak. Harga FOB lebih rendah sekitar 20% daripada pembekal lain, margin keuntungan tinggi. Customer service boleh berkomunikasi dalam Bahasa Inggeris dan Bahasa Malaysia, masalah diselesaikan dengan cepat. Akan bekerjasama secara long-term, harap syarikat akan melancarkan lebih banyak pilihan warna kemudiannya!
