    16730 is rated 3.4 out of 5 by 5.
    Rated 5 out of 5 by from as described exactly as described, and the unit i got was the update version where the brass fitting was machined in about an 1/8" so the thread in probe is less likely to break off like my old one did.

    Rated 5 out of 5 by from works as it should I like this switch better than the one it replaced. The old switch worked off the ground side of the circut. It was suppose to turn the fan on at 180 degrees: but the temp. allways got up to about 220 before the fan came on. The Derale comes on at about 180 as advertised.

    Rated 1 out of 5 by from Stud to small The sending unit stud can be broke off with finger. The stud is like a 10/24 thread that threads in the the adaptors. Not happy with the durability

    Rated 1 out of 5 by from I bought 3. The first one turned on the fan at 200 Deg. and off at 180 Deg. The second one the adapter wasn't threaded and the sensor was loose. (?) I returned both of them and have since ordered another. I sure hope it works. I haven't been able to drive my car for about a month now.
