Finish is kinda rough, burs everywhere, and not machined right. I figure Tesa would have a better quality control than this. On the plus side, this case is USA made though, only reason for 2 stars. Going to go blow twice as much on a starrett now. They're expensive but their quality is always amazing.

I am a machinist. Quality is important to me and so is Made in America. I chatted with customer service before I purchased it. She assured me it was made in USA based on the description of the company. So I ordered it. Received it today. Quality is terrible. The milling of the parts look like somebody used a coarse file instead of a milling machine. Burrs everywhere. The riser blocks don't even fit together!I am angry and very disappointed in a product from a company I once considered quality. This piece of junk was clearly made in China by the lowest bidder with no quality control. China can make quality products but this is not one of them. Returning it.Ordered a Starrett jack set. Sigh

I was looking for a way to support an AR15 barrel while I dimpled it for a gas block on my drill press. This is exactly what I needed. A piece of angle c-clamped to the table and this jack allowed me to center the dimple jig with my cross slide vice and support the barrel to adjust for square.

The screw jack works and looks to be good quality. The country of production is however missing from the packaging. Make of that what you will..

This is a great set, And for not much more than a chinese product. Get a couple of these and you can stabilize most any workpiece on your machine. This was an additional set to compliment the three I already own. Two of which are over 10 years old and still work like the day I got them.
