## Customer Reviews

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    High quality proto!
  

*by S***E on Reviewed in the United States on August 6, 2019*

Ordered this to replace a proto j1193-A that I misplaced at work. :( I work in a compact loader assembly plant and use a 9/16 wrench all the time and 1/2 here and there so a combo wrench has been a dream for keeping in my pocket. Description of this wrench is misleading. It says the heads are 0 offset, which happens to be false. See attached pics. Still a great wrench by all means, after all it is proto! I will definitely be keeping to add to my collection. But if you’re looking for a straight 1/2 & 9/16 combo wrench try the other one I mentioned. I’ve already ordered 2 more of those to have on hand!

    Works Great!
  

*by C***R on Reviewed in the United States on September 12, 2020*

This is a well built and works perfect for my needs. I use it on our batteries for our Travel Trailer, and it works great!

    The ratchet works great and is very strong
  

*by C***Y on Reviewed in the United States on December 29, 2017*

I was let down at first once I opened the package and discovered that both ends are angled but that does make it easier on your hands.The ratchet works great and is very strong. The splines grab nicely and do not slip. Due to the angle of the handle when you’re  pulling on a fastener it causes the splines to twist on the fastener unless you’re compensating somehow.
