Product review (3 stars): Drilling out the rivets and mounting it on my original bracket was easy (if you have the tools)
The mounting plate/ bracket of the thermal cutoff was not the same as that of our dryer (but was as pictured in ad).  Drilling out the rivets and mounting it on my original bracket was easy (if you have the tools).  The tree stars is because it lasted about a week.  I have now done a more thorough cleaning of exhaust duct and willing to give it another shot.  If the premature failure is on me then this deserves a higher rating.

UPDATE:
Purchased same set and again replaced the provided thermal switch mounting plate with the original (that fits the dryer).  I noticed that the temperature rating of the first switch (that failed; ref. above) is 190 deg. C, while the replacement (same part number as the first) has a temperature rating of 165 deg. C.  What's with that, when reordering the same part?  You will not see this temp. rating unless you remove the mounting bracket.
According to the stamp on the (original) dryer mounting bracket for the switch the set point should be 350 deg F (177 deg. C). "INTIOL -0954  PART NO 3389946 L350 F".  Time will tell how long this one lasts.
