Always happy with this product, used it several times. Though it would be nice if the LEDs and sensor were on the same board as the rotary encoder instead of the motherboard :)
I bought this product many times. Every time I am very happy with it. I always remove the LEDs and Receiver IC to mount them to the front panel of my project. It would be very nice if there was a version where these components were on wires providing freedom of mounting options.
