I tried to make a gate with the force relay, and it's really irritating, that you can't pull them with sticky pistons. Also, the bounded block can't push other blocks. If the force relay would push a block, it will get destroyed without dropping itself. When a non-extended-piston-block pushes a force relay, the force relay will glitch 1 block down.

For writing faults I blame my german origin.

I can't do anything about any of that. Pistons in minecraft are super obtuse.
