First, this remote is an aesthetic success. Touch plastics seem weaklings but after four months of intensive use, they do not shake! All my instruments have been recognized (string, receiver numéricable, PS2, TV, computer). Some macros to turn on different devices at the same time do not always work (this may be the receiver and the remote control is not involved) The backlight is enough to see well in the dark without blinding. Battery life seems quite correct, in 4 months of use no sign of weak batteries. This is a good device, rather easy to use, quality, I recommend especially on Amazon, at the best price!
