Great store. Seller dispatched the item fast, placed order on a Sunday evening and it was dispatched early on Tuesday. Packaged with a layer of bubble wrap. Received in excellent working order. Great functionality. Instructions are in Chinese but I was able to read parts by using Google Translate.

Todo perfecto, la unica pega es que el manual de instrucciones y los interruptores figuran unicamente en chino, el vendedor se ha comprometido a enviarme un video explicativo pero estaria bien que adjuntaran las indicaciones en otros idiomas. Muy satisfecho por todo, lo recomiendo.
