## Customer Reviews

### ⭐⭐⭐ 







  
  
    Low price point seems to be a reflection of quality control effort
  

*by R***N on Reviewed in the United States on April 15, 2020*

While it was safe to assume that these brackets would be cast (instead of extruded or wrought) aluminum given the low price point, I was rather disappointed by inconsistent threading for the set screws.  Of the package of 20 brackets, 10 had two properly tapped holes, 8 had holes tapped that had retained chips or burrs that requires chasing with a tap before the fastener could be threaded-in, and two were each missing threads altogether on one hole.  While none of this warranted retiring the product for a refund, the needed rework was a waste of time and would have been even more problematic if I hadn't already owned metric taps.

### ⭐⭐⭐⭐⭐ 







  
  
    Essential for assembly
  

*by G***3 on Reviewed in the United States on March 6, 2021*

A must-have for building corners with t-slot and v-slot. These are smooth, nicely coated, and don't (yet) bend. I was annoyed that the set screws weren't already installed, until I realized there are different orientations that require set screws installed in different directions. Play around and you can make inside, outside, even sliding connections.

### ⭐ 







  
  
    Doesn't fit 2020 extrusions without grinding
  

*by M***L on Reviewed in the United States on July 18, 2019*

Used on Tevo Nereus. Did not fit without modification.
