Very nice and accurate!!

I was pleasantly surprised at how good the quality is, especially for the price it’s sold for.Very happy with this product.

It's ginormous (!!) and very sturdy but hard to carry around. I use protractors for drawing, but this isn't something I can toss in my pencil case, and it's a bit too heavy duty for drawing on certain papers. It seems like it's more so made for construction material like wood.The pencil holder is small and not very adjustable, so none of my prefereed pens fit in it. I'm pretty sure TSA would take it because the pointy edges too, so don't try taking it on a plane!It isnt great for me. But it's a great buy if you're a professional, or otherwise need a heavy duty compass tool or a home defense weapon. Lol!

I just got this compass and it was a pleasant surprise. Hefty metal construction and it has positive thumbscrew to keep the distance adjusted. An interesting surprise is the warranty that says they will replace or refund your order NO MATTER HOW LONG YOU OWN IT. Hard to beat that!

I needed a compass for a home carpentry project. The smaller size would have worked well for this project but I decided to go with the larger size so it would also work for a potential upcoming project. It was easy to set the points to the correct size using an architect's scale but holding the point and dragging the scribe point with the circles being rather small could have benefitted from a third hand to help steady it. Having only my own two hands available at the time, I scribed a portion of the circle and then repeated, overlapping each portion of the arc until the circle was complete, meeting the original scribe mark perfectly. The scribed circle measured correctly, as did several other arcs made afterward. If you do most of your work on your own and don't need the large size, I recommend considering the smaller size but if you need the larger size at times, go with the 12" version and be patient and careful with scribing your arcs. 4.5*, rounded up.

Very well constructed. Tight pivot point. Highly recommend

Used it maybe 3x before the spring went flying across the room. The release for the quick open and close is lost forever. Not happy with how this is made. Literally all I did was pick it up and try and to adjust it. Nothing. Have drawn 5 circles before the thing popped. Now its all floppy and possibly useless.

Review for the 12" compass divider.This divider is very sloppy, I can move the two halves about 1/4" (See the photos) Additionally most of the grinding looks like it was done with an angle grinder. This is not a precision machine tool, There are gouges in the metal, and the rivet that holds the two parts together looks like it was hit with a hammer multiple times. Perhaps, in some vain effort to make it less sloppy.I returned it and will order a more expensive/ Better quality one. I gave it three stars as it does function as a measuring device ( You can set the points on the two areas you want to measure, lock it down, and then measure the distance between the two points.) But it is not useful for drawing circles, nor for stepping off a consistent location for drilling holes.
