Educate me on spyder robotics thermostats?

Can I ask the significance of the metal probes? Is it worth buying afterward, as an upgrade to the standard ones I'm already using?

From their site it says "These new steel tipped probes are epoxy sealed to increase water resistance. The steel tip also transfers temperature change faster which can be beneficial in setups where the probe is monitoring air temp like incubators"
