Why? Auber doesnt offer any special warranty on them? bunch of folks reported being told they were SOL when auber stuff has failed... if not for better support why pay triple $$ with shipping for the same thing?
I would buy these as well as the generic pt100 sensors form ebay and save yourself the extra $40 one temp probe and ssr from same manufacturers would cost you from auber with middleman convenience markup here... Buy your temp controllers from auber if you want, thats their specialty (EZ boils are nice)..
I went with mypin td4s myself which worked great before switching to ezboil and then brucontrol.
