## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    Exactly what I ordered
  

*by B***E on Reviewed in the United States on November 20, 2022*

I think that it is perfect. I think people are driving slower.

### ⭐⭐⭐⭐⭐ 







  
  
    Same signs as the State uses.
  

*by P***D on Reviewed in the United States on August 27, 2022*

I orders 3 18x24 speed limit signs.  They came in a short time and were the same reflective signs my State uses on the highway.  The holes were already drilled and easy to install. They were packaged properly and delivered to my front door. All 3 came to about $100, which was a more than fair price.

### ⭐⭐⭐⭐⭐ 







  
  
    Easy to see day or night
  

*by J***N on Reviewed in the United States on February 26, 2020*

This sign is mounted on a metal post at the entry of a driveway lane to four houses.  Easy to see in the day and very hard to miss in the headlights at night, VERY reflective!  This sign is the "real thing" and very durable.  Has made drivers slow down considerably on our lane.
