## Customer Reviews

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    Very servicable.
  

*by J***T on Reviewed in the United States on May 6, 2021*

These wrenches are not the best quality, the casting and finish could be better, but they are more than adequate for occasional DIY work. I don't need flare wrenches very often and these work great for me.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    These work perfectly
  

*by H***. on Reviewed in the United States on October 30, 2018*

I was concerned that a cheaper set of flare nuts would not be able to remove the hard brake lines on my 2006 (12 year old) Mini Cooper but the 14mm performed flawlessly. These are also perfect for bleeding the brakes using the 10mm on the bleed nipple. 5 stars for me and a must have for anyone wrenching on their cars.

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    Worked like a wrench
