## Customer Reviews

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    I'm happy with this window guard.
  

*by R***L on Reviewed in the United States on August 14, 2021*

The dark bronze color blends nicely with bronze framed windows and the product is much sturdier than one I had previously ordered.  Also, the top bar reaches almost  half way up the window opening so it provides greater protection for young children.  I did not install so I can't comment on any installation issues.  I have a solid cedar home so 3" screws were used to attach to wall.

### ⭐⭐⭐ 3.0 out of 5 stars







  
  
    Repurposed for intrusion deterrence
  

*by M***R on Reviewed in the United States on December 10, 2019*

The item was packaged with the wrong instructions. However, it's a simple product so I had no problems there. It is labeled with a warning to not use with casement windows. The vendor did not display this warning on amazon.com and I would have been within my rights to return the product. This warning is irrelevant if the use case is intrusion deterrence on a ground level casement window. The item is virtually identical to products meant for intrusion deterrence. I selected this product because of width - the normal vendor I would use does not support wide windows. Installation was easy as expected. The windows are taller than optimal, so I added an additional bar above this unit which could be removed for emergencies, but is not necessary to remove in terms of escape from fire. Pity that the Segal company won't provide instruction  or product to serve markets other than child barriers. The 3-star rating accounts for my frustration of dealing with the seller and the product.

### ⭐⭐⭐⭐ 4.0 out of 5 stars

This windows guard looks heavy duty, but the instruction of installation not that clear.
