All my 5 devices I've tried, were detected easily and work perfectly.
Keys which he had not the same, were programmed in just seconds.
Even those in the previous versions, battery-eating activation in motion and vibration is gone, very good !!
Negative is the design and size.
Rear is round the battery compartment and that's why the remote control is always at an angle at the table. Disregarding no photo!
And the size makes it sometimes impossible the remote control with one hand to operate, sometimes it takes the 2nd hand!
That's why only 4 stars!
