Probes with center LEDs and emulating keys

Has anyone had success with probes like these? Seems that the recess in the center completely defeats the Flipper, as I was unable to make contact with the data pin both in the wild and under test conditions (basically, buying the probe, hooking it up to a Raspberry Pi and looking for slave devices to appear).

You can buy an iButton shell and connect wires from GPIO pins 17 and 18 to make contact with those readers

I don’t think I’ve seen the actual casings being sold separately. More realistic would be a RW iButton. Thanks, though!
