+:
generally fast switching, good image quality, functional remote control
-:
* Groundless defect after only one year (low mileage)
* Previously repeatedly crashes (Disconnection of Power necessary)
* Some transmitters longer channel change because supposedly no signal
* Awkward assignment of the remote control
* Complicated menu guidance, poor information board
* Worst transmitter programming (eg DasVierte, GIGA never epmfangen)
* Total half-baked idea (eg crashes when Soft-Update)
* Grottiger Support
Conclusion: for 20-30 euros, the DX-15 would certainly be unrivaled. As one of the 50, - Euro gets but much more user-friendly equipment from established manufacturers (also here at Amazon), I say: "Stay away!"
