## Customer Reviews

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Worked fine on microwave overheat circuit
  

*by D***R on Reviewed in the United States on March 20, 2023*

Easy install, I used this part to replace a different spec in an overheat safety circuit - works perfectly.  Additionally this part will reset itself after it cools down (I tested this feature) whereas the part I was replacing was "one and done."Cheap - but I don't know what I am going to do with the other 4! (junk drawer I guess...). Would be nice to be able to buy just one.

    Exactly what I needed to fix my clothes steamer!
  

*by M***R on Reviewed in the United States on October 17, 2024*

Saved me a lot of money not having to buy a new steamer. This was an easy fix! Fantastic build quality and functionality. Accurate product description.

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    QC could be better, but not a huge deal.
  

*by R***C on Reviewed in the United States on January 23, 2022*

Bought these to repair a small 12v tire air pump. First one out of the package did not work, but the next one worked fine, and the remaining ones do as well (tested them with a meter and heat source). Price is reasonable enough that I am not concerned about the single defective unit. Just posting this in case it helps someone else in the future.
