I am wanting to add a tool setter to my machine with a limited budget. Anyone tried these?

SHINA SK-66 CNC Automatic Tool Touch Sensor Normally Open with Blowing Setting Gauge Z-Axis Presetter Locator with Stroke 5mm for Mach3 etc https://www.amazon.com/dp/B01MYGDU3K/ref=cm_sw_r_cp_api_glc_fabc_bB78FbR4YG488

Or, anyone had good luck with one of the imports?
