    Locks did not work….
  

*by C***Y on Reviewed in the United States on February 5, 2024*

I initiated an eligible return of this product. The suggested box did not fit properly to these locks so my contractor could not use them as the rubber seal would not fit around opening. It’s been over two weeks and I've not received a refund credit.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    As advertised
  

*by A***R on Reviewed in the United States on February 21, 2024*

Lock works well. Had to watch the install video a few times to figure out how to move the handle to the correct position and to install correctly. This is the 2nd handle I bought for 2 different outdoor gates. The first is 4 months old and is handling the outdoor weather well. Nice that no batteries are needed. Great item for the price.
