compass set
Accurate, easy to use. Delivery poor. It was delivered next door, despite the fact that we were in at the time.

Not a geometers dream!
This item fell apart after two uses. It has a design fault. There is no rivet or threaded screw holding it together. The spring clip (the circular metal band at the top) holds it together. However, when opened to it's fullest extent it falls apart. Regrettably it's very hard to reassemble. Not recommended.

Great compass
A very unusual product but is really good because it does not slip and lose the radius and you can get very precise lengths with this! definitely works well and turns some heads

Simple but good, solid quality.
I like it that it's simple with no bells and whistles like some others. It's sturdy, 100% made of metal but not heavy. It can operate in high precision even for professional use and it's ergonomic (i.e. the top tip is easy to twist around).

Not had this sort of mechanism before and now I’ve tried it not impressed. Fiddly. Also metal looks and feels cheap.

La calidad es pésima. Se rompió después de solo dos usos. Intentamos devolverlo, pero el plazo de devolución ya había expirado. ¡A este precio y con esta calidad, no queda más remedio que tirarlo a la basura!

The Mr. Pen Professional Compass for Geometry offers great value at around $9. It features a sturdy metal construction that remains stable during use, with tight screws ensuring reliability. The compass marks materials like leather cleanly, thanks to a sharp lead point, and there's plenty of lead included for extended use. I have only used the compass for a bit of leather marking, but will update if issues come up. One minor downside is the mustache logo, which may not appeal to everyone. However, considering its performance and durability, there’s little to complain about. Overall, this compass is an excellent choice for students and professionals alike, providing an effective tool at an affordable price. Highly recommended.

Sturdy and rigid. A real tool. Not like that flimsy piece of junk my daughter was using before. Geometry makes sense to her now!
