Unfortunately, wasted money..
The battery of the monitor never lasted more than 2 hours and the monitor didn't work while it was charging. So, you had to have it with the battery.
Also, the signal in adjacent rooms was simply tragic, it constantly had interruptions and lost the image.
Finally, both chargers broke within a few weeks of use.
Overall, we used it for less than 3 months, and only to say that it made its money back, which never happened.

The whole package was so wrong that I didn't even bother to run the warranty, as something else would break any moment.
I don't even know why they still sell it.
