Sensitive as the camera shutter

A switch is sufficient long to trigger the camera within a reasonable distance to the tripod-building can. Plugging and releasing the shutter button on the camera slot works backlash because nothing rattles. The pressure point is just as sensitive as the camera shutter, make or use auto focus, then press fully to take the shot so pressed halfway measure.

Here I trusted precaution the original product, is probably more reliable than a product of an inexpensive third-party. The device is of the haptics in any case usual Canon-like.

The price for that matter. If you consider that it is a couple of insulated wires with plug and on-off button.
