Processing seems very solid and overall we are very satisfied. Now the negatives:
- You should recharge the batteries / replace as soon as the charge status display no longer indicates fully charged. Depending on the operating mode it is possible that less than an hour left. I recommend the use of NiMh batteries (AAA) with a higher capacity than the Mitglieferten batteries.
- In any case, in our device coordination between the devices with activated Range control did not always work. This works as follows: Both the transmitter and receiver to send every 30 seconds a "I'm here" signal. When these two signals (but not at exactly the same time) are within 5 seconds of each other, the devices display the "In Range" signal. According to the manual this time difference should thus be possible to achieve that the two devices are turned on within 5 seconds. But this is not the case in our device, the time seems to be random. It follows that you need some luck to turn the device so that the signals are maximum 5 seconds ausseinder and thus the range control is working properly ...
- In general, the manual is a bit strange written (See also the last point) - but you get so rightly ...
