## Customer Reviews

### ⭐⭐⭐⭐⭐ It works, although the beeping is difficult to hear
*by T***E on December 12, 2023*

The only con I have found while using this is the beep is far too quiet. In my shop I cannot hear the beeping unless all machines are off and I am the only one in there so I watch the DRO screen as if I were setup on overwatch. My hearing is far from perfect (jet engines and automatic rifle fire does that to ears) but I have no problem hearing other electronic devices that beep. Other than that, this little torque box is good to go.

### ⭐⭐⭐⭐⭐ Tightening down the hatches
*by M***C on March 17, 2023*

This is a great design and build quality. The only thing I don't like is you need to unscrew the cover to remove the battery. I don't use it that often, so I remove the battery when not in use. Other than that, I like the metal case it comes with, and I like the way it works. I recommend.

### ⭐⭐⭐⭐ Works great
*by B***L on August 27, 2024*

I checked my torque wrenches with this & is easy to use, I thought the case was something other than plastic because all the others, people were complaining about the cheap plastic case. Well, this is plastic as well, if I knew that, I would have bought the cheap ones. As long as you treat it like eggs, you should be fine. If you drop any torque wrench, it will be damaged internally it might look ok but it should be tested before use.
