### ⭐⭐⭐⭐⭐ Good for the price
*by E***Z on January 26, 2020*

I give 5 stars to this item due to it's balance price quality even though, this jaw is very light and simple it is a safety device and the idea is to use Lockout Tagout system which no one should try to break one. Considering that this item works for what it was made and for a low price
