Does the job perfectly 1

Overall impression:
The product fulfills its purpose perfectly. After you insert the supplied batteries (also on the transmitter's battery compartment with only one screw easily accessible) to synchronize the transmitter and receiver station immediately (max. 30 meters distance)

I can only recommend the device, if you're looking for an affordable gage that via radio Transfers the amount of rain and the temperature outside, and if you do not need a complete weather station.

Operation:
The operation of the buttons on the front, including the setup is intuitive and easy, and actually durchfuehrbar without Manual.
No problems with the setup and sync of transmitter / receiver as with other manufacturers (no reset required).

Features:
- Display of inside temperature and outside temperature (change the display via a button) in the top of the display
- Outside temperature sensor not included as a separate sensor but the rain collection cup
- Display of date, time (exchange via a button, then display of rainfall) in the center display area
- Display of rainfall (change the display via a button) in the middle display area
+ Total rainfall (since reset)
+ Rain in the last 24 (not with day / date changes)
+ Rainfall of the last hour
+ Rainfall of recent rain fall
- Display of Rain History
+ As a quantity (in the central display area) and bar graph (the bottom of the screen)
+ The last hours
+ The last days
+ Weekly and Monthly
- Min and Max temperature display
- Min and Max alarm rainfall
- Min and Max alarm for indoor and outdoor temperature
- Setting in mm or inches; Degrees C or F; European or American date
- Display only in English, not in German (does not bother me); So no voice dial, but Manual is multilingual

Only negatives so far:
- Reset only the total rainfall possible in order you have to briefly remove batteries back afflict the individual amounts;
- You can see the total amount of rainfall and current rainfall is not at a glance, but that would further display line requires, and instead there is a bar graph representation of the last rainfall (hourly or daily).
- Supplement for a few weeks in use: it's a bit unusual and not intuitive that the rainfall (ie at midnight) will not go a day but that there is only the "amount of rain the last 24 hours"; This is quite unusual as this value does not start again the next day at 0, but decreases every hour (and new onset of rain this value increases again) ...
