This product is exactly what I need. It is suitable for my small restaurant. It is easy to operate, responds quickly to receiving information, and solves my problems very well. It is small and light, and I am very happy to buy this product.
No me a dado ningún problema tiene buena covertura de señal mi restaurante es de dos pisos y cubre perfecto... llevo usándolo ya un par de meses... y todo en orden
The product is good quality, and “easy to use” until you want to turn down the volume, I couldn’t find the manual, even I tried to find a video In YouTube but I couldn’t find it. I still don't know how to turn down the volume
