12” Compass
If you need a 12” compass, look no further. The product was much higher quality than I was expecting. It works perfectly! And it is refreshing in today’s market to have a company sincerely appreciate your business. I would purchase from them again without hesitation.

Robust tool, works well, part fit could be improved
4.5, stars, I really like the heavy duty construction, though tolerance is a bit off and part of tool collides slightly while opening so it’s hard to make small adjustments around a certain angle. Circles are accurate. All in all good product though

High quality compass
A professional compass, with real weight. Holds in place even without the lock, we’ll have to see how it lasts. But seems very well made, the edges on the steel are pristine. Points are definitely sharp. Practically a surgical instrument.

Nice LARGE Compass is Fabulous for Large Circles
Awesome LARGE compass works fabulous at drawing big circles. Very well constructed and easy to use. Great value for the price. Highly recommended.

Not professional, not even percise
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.

This pro compass is the finest quality tool that I have in my collection, it will last me my life and the lives of any other people that have it after I'm dead, this item was a justifiable use of fuel, because it's well made and made without designed obsolescence, unlike the crap tools from the local hardware store, Jab saws, with plastic handles and little vice that break as soon as you use them, and every poorly thought out battery powered junk tool, this tool is fine crafted and a solid tool for the ages.

Es un buen producto, llegó tal cual el modelo mostrado en las fotos, material resitente y de calidad, quizá sea que el me me enviaron tenía un buen tiempo en stock y el material en algunas partes presenta unas pequeñas manchas negruzcas; es el único detalle, no afecta su funcionamiento. Ideal para tener precisión en la medición y el trazo.

こんなに大きなコンパスがあったのを知りませんでした。大きな円が描けて便利、簡単に六角形、八角形も描けて最高。 鉄板に直接けがきもできます。

Heavy duty product, some edges are a little sharp - just touch up with a file.
