Like it very much, everything works perfectly, even on the go! What I also like is that you are not tied to a company Producke probes of different companies are supported. For this price a very good device! What could versessern is a feedback is whether the command ausgefürt, just by the way would be great, I send the command from the way of safety reasons three times, and so far everything was switched when I got home! ! ! What I did not like the one for the app still times 6, - must pay, this app need but only people who have this device, so you should use the purchase price by 6, - increase and good. Operating the device with two mobile phones and so I was ordered again 12, - put it, that must not be! !
