I bought this single probe as a replacement probe for my iGrill mini. The one I've been using has worked perfectly for almost a year; but i know they can fail after awhile.  I love my mini and use it for just about every grilling. So I needed a backup. I take care not to kink the cable, and i clean it off with a dry, slightly abrasive sponge. The original is still ok, but i don't want an inconvenient surprise.
