### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    good product
  

*by M***K on Reviewed in the United States on January 22, 2013*

The perma coils are good but I wasted through a whole batch of them before I realized that the inserted was the wrong size.  I contacted the company and they made it all right.  very good customer service.  Eventhough I was initially frustrated I really felt taken care of when it was done.

    Saved my Brake Caliper
  

*by B***T on Reviewed in the United States on September 6, 2013*

Stripped my brake caliper, used this to repair it. The tap worked great and I got the coil to thread, but the precoiler just made the installation harder. The t-handled tool I have for other helicoils in much easier to use

### ⭐ 1.0 out of 5 stars







  
  
    DOES NOT WORK!!! Tap is not a thread repair tap.
  

*by J***H on Reviewed in the United States on October 26, 2015*

This tap does not work correctly. I tried for hours to get a hole in an engine block to thread and insert the tcoils, and failed at all attempts. I was able to get a larger bolt in without the thread repairs (as an experiment), and I suspect the tap is not a Thread Repair tap,, but instead just a normal tap relabeled in a thread repair size (BUYER BEWARE!)I broke all the repair coils trying to get it to insert. If the tap is the wrong size, the coils will not go in.
