## Customer Reviews

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Worth the money
  

*by A***R on Reviewed in the United States on December 28, 2017*

Excellent in all areas. I checked the measurements as someone mentioned that they were not accurate.Mine is accurate when matched up against all of my carpenter's squares and rulers.I like that the 1/4 inch bit driver is also accurate as almost every tool that I have like this is .035 inches too small.What I don't like is that it appeared to be used - pencil marks all over both sides of it.I am not able to rub them off without altering the shading of the tool.So mine, which was supposed to be new, seems to be used instead.

### ⭐⭐ 2.0 out of 5 stars







  
  
    Unfortunate
  

*by P***D on Reviewed in the United States on September 12, 2017*

Well thought out product, not well executed. Either this ruler was printed slightly too small or every other ruler I own is slightly oversized. A 20 dollar ruler should not be less acurate than the wooden ones they give children at school.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    It also appears to be machined well and has a nice solid feel
  

*by D***K on Reviewed in the United States on December 19, 2017*

No serious issues. I see someone said the measurements are off... but I did a quick comparison and mine doesn’t seem to be off at all. It also appears to be machined well and has a nice solid feel.
