It's really a good product, it's quite big and very well made. Old fashioned goodness

I was surprised how sturdy this thing is. And having the locking screw makes sure the adjustment will not change.

Exactly what I was hoping for. Holds a standard pencil. Sturdy enough to last a lifetime for my purposes.

Being Chinese made you can only expect so good of quality. The entire thing has fairly rough grinding marks and 4 edges had burrs that were sharp enough that I had to file them smooth. That being said, it really doesn't it prevent it from performing adequately. The pivot is good and tight and all the threads work well. It seems like it will work the way it should.

I purchased the 16" version. It very adequate for laying out arcs for reference points in my paintings and geometry projects. I am pleased with the overall quality of this compass. It sturdily made and is robust at the hinge point. No wobble. The pencil mount is OK. The finish is adequate for its intended use. The two sharpened points on the legs are ideal for long divider measurements and will be handy in the wood shop with pencil removed.Having the 16" compass now is persuading me to get the 12" compass as well to fill in the middle ground between this quite large compass and standard draftsmen compasses found at office supply stores. My "accuracy" score of 4 stars is reflected only by the use of a standard pencil as the marking lead, and is only as accurate as the user. For my purposes it is very good.

I purchased this compass so that I could make full scale 22 inch diameter drawings of a composite flywheel I am designing in order to instruct the technicians who are building the flywheel in the location and orientation of the composite fibers. This project involved making numerous concentric circles on large sheets of vellum or bond paper with accurately spaced distance between each circle. I tried several other compasses with clip-on extensions and they proved too rickety to draw accurate large circles. This compass is exceedingly stiff and strong. Once you set the radius desired, it is not moving and the only inaccuracy is in how the pencil lead wears down. I tried to use a drawing pen but found that it was too sensitive to the angle of the compass arm with respect to the paper surface, and would skip irritatingly. As long as you keep your pencil sharp and tightly clamped in the holder, you can make as many large circles as you like with excellent accuracy.

Well, I wanted to make a really large circle for my artwork, but I had no idea from the photo what a humongous item this would be! I can’t really fault the item. It will be great for woodworkers. As far as for artwork, I believe I have a permanent hole in my Gatorboard table. Also, I have a huge hole in my very expensive watercolor paper. Still I gave it 5 stars because the product looks good and performs well. It could also be an emergency weapon against any attacker. NOT for children! The points are really sharp. It might make an interesting realistic rendering.

This compass works perfect for drafting your own stencils and or shaping mendela dot art.A very durable and well made product that offers ease of movement and variable size pencils, pens and painting accessoriesI'm very happy with this compass and recommend it to my fellow crafters.
