They do the job and are a great price. I was concerned about multiple triggers from a single "bump" of the sensor, but there's a built-in manual adjustment for this and it's effective.

These are fine. You may need to adjust sensitivity by turning the potentiometer. Could take some trial and error to dial them in, but they're convenient to use with Dupont connectors.

Simple sensor. Simple function. Good enough. I have no problems with these.
