Not only is this a great little compass but the company is awesome. I lived the little personalized note that comes with it. It works great and adjusted smoothly and stays where it's set. It feels strong and durable in your hand and the pivot point tip is sharp and stays in place. Only down side us mine came without the locking nut on the little screw that holds pencil holder in the frame. At first, I wasn't concerned about it, but I emailed the company anyway, they returned my email promptly and never questioned my claim and sent me not only one locking nut but 3 sets of nuts and screws. Would definitely recommend

Finally—A perfect compass for holding a pen. I draw geometric art and I’ve been struggling to find the perfect compass to hold a pen securely and with legs that won’t collapse as you draw. So much better than the style that you have to change out. And at a very nice price.

I like the adjustable versatile features. Can adjust and fix the angle from the spinning wheel and keep it firm, while other compasses it will move out of angle when you are rotating it. The only part I didn't like it's the section that holds the pencil because it's made of plastic. Wished it was made of metal like the other parts.

This is great for craft work or other small projects.

I use this compass for my mandala dotting art and it is perfect! It is a great size, feels like good quality and is easy to use with a reasonable price.

(updated) Impressed with the company, it not the product. At first I loved the compass, and the main structure of it is still perfect. Bought in December, in May it stopped being useable. I had fairly limited usage and stored it in the box when it was not in use. And yet, the solid metal parts are amazing and perfect, but the part that holds the pencil is a plastic screw in a plastic sheath and that no longer can be tightened thanks to the plactic giving out and not holding tight so the pen/pencil will just slide out at random times, which changes the diameter of the circle and makes it utterly useless. If I tighten it more, the screw pops over the threads.I reached out to Mr. Pen and then immediately refunded my order. AND I had also left a 1 star review - which they promptly responded to with an apology and a direct message offering me a refund. so now I'm taking the average. 5 star company, but not sure this compass is a five star product. I ordered the same one again after the refund because it has all teh features I want, except perhaps durability. Time will tell on round 2.

This one has great build quality and worth the price

I've been looking for this compass for a while. Finally, I have a solid, accurate compass that will hold a Koh-i-nor Rapidograph technical pen to ink perfect circles. You have to take the outer barrel off the pen nib and tighten the holder around the ink cartridge collar, but it holds it tight and doesn't slip. Perfect circles, every time. Excellent tool and super sturdy.
