Excellent quality. Small and lightweight receiver.
I can also confirm that this works with the Absima SR2S stick radio (essentially a re-badged Flysky system). This receiver is considerably cheaper than the Absima branded one, but is virtually identical. The same binding procedure can be used.
Tip : if using in an electric RC car with ESC, set the failsafe for the neutral throttle position by holding the failsafe button for more than 2 seconds (red led will flash to store neutral position).
