Very reliable device and very affordable. The downside is that it only has instructions in English, and if you don't know it very well, you don't fully understand its function and can't take advantage of all its capabilities, staying at the basics. You can find translated instructions on the internet, but using Google translation doesn't help much.

Worst purchase I have made. Button 8 came broken, stuck down. When closing the headset, it makes a strange noise that lasts for 10 seconds. The phone smells like the worst plastic I have ever smelled. The speakerphone is excessively loud and you can't have any privacy because it doesn't lower the volume. I wanted to hear it, not the whole neighborhood. I'm looking for how to return it.

I order this phone. It arrives damaged. I request a replacement.
It arrives again, again damaged. Chinese of the worst kind. Stay away
