The image quality is good, but it disconnects a lot of the Wi-Fi and goes offline. Battery life is a weak point. If it is not defect of the device I received… the charge lasts a few days. Looks more like low-quality cell phone charge.

Perfect, but be careful it calculates the current that passes in both directions

Seemingly all horsho

Good product and good seller, very fast delivery

Poor battery. After a month, it was necessary to charge. Coverage can be, although it shows 50% this connection is interrupted. The Bell does not ring on the phone, but it says that “you have a guest”. Sometimes it happens that the phone rings me, but not always. I don’t know what it depends on.
A caller module connected to USB at home is some total failure. Calls when he wants, so you can’t rely on him.
So the frenzy is not there, but maybe it is a matter of going deeper through the settings, although I think I have already done it and have not come how to correct the bad things
