RF remote control module review

This RF remote control based on IC PT2272-M4, can used with or without Arduino. it is very easy to use.
There are one channel, two and four channels remote control module in the markets.
There are 3 types modules in terms of switching method:

1-If the module made by IC PT2272-M4, that means the output will be HIGH when you push the button and be LOW when you release the button.

2-If the module made by IC PT2272-T4, that means the output will be HIGH when you push the button and be LOW when you press the button again.
3-If the module made by IC PT2272-L4, that means the A-output will be HIGH when you push the A-button and be LOW when you press B-button.

By this remote control you can run any load from 50 to 100 meters.
You have to add a transistor and relay(as figure) for running 110/220v AC or some DC power LEDs.
