10 out of 10!
I've become so accustomed to photos that lie and cheap materials etc. Opening this up to find an entire kit of everything I could need, and the compass itself is absolutely beautifully made. My grandad was a draftsman and this tool feels like the kind of quality he used to use, and I mean that in as the highest compliment. Thank you for shattering my low expectations Mr Pen and co! :) (I got the rosegold, it's really pretty)

Economical Yet Functional
This is not a professional quality tool and is limited on the min/max width. It's an economical tool that does what it's supposed to do. It doesn't lock, strictly speaking, but the adjustment wheel is firm enough. It comes with 10-15 replacement leads. Comically, two of the three little vials containing lead were empty and their contents were rolling around in the little bag. One of them still had the cap on it, so I have to think the person packing it was all out of effs to give that day and just dumped the required number of parts in the bag instead of trying to fix it. Two steel tip replacements, two little tightening wheel replacements and strangely no little screw replacements. A mustache sticker and a hand-written thank you note. It's stable enough for what I need to use it for. Doesn't have as much flex as some folks have reported. But if you're looking for a tool with tight tolerances and high production value for architecture or engineering use, go spend $100 - 200+ on a different product.

Does the job, but clearly a low-budget item
This compass does the job of a compass and does it very well. They even throw in some extra lead and a little storage pouch too! But while it does its job well, it doesn’t really scream “quality” at all. A big disappointment was when I first saw it and noticed it’s painted. Not anodized or coated, it’s paint and it’s obviously paint, with small lumps and uneven spots. In my opinion it doesn’t look much like the images other than in shape, with the color not looking close at all. The other point against: the adjustment screw is not centered between the arms. If set as wide as possible this is very obvious and is likely limiting the total amount of adjustment. It’s certainly not a professional-level product but then again it’s not a professional-level price either. It’ll draw a circle or an arc, help you measure things, and even scribe some things like I have, but it won’t win any awards for build quality.

Great value for the money
I am always impressed with merchandise from Mr. Pen. As usual, this compass, fits my need perfectly. The addition of the extra pencil leads and the life time lead replacement is a bonus. Its compact size and the ability to make up to an 8 inch circle gives me the flexibility I need. It works well.

Buy this compass!
Buy this one. You'll be impressed with quality. Bonus vials of a lead, spikes and the tightening wheels, as well as a cleaning brush were also included. I have never purchased a compass with all these accessories, not even the higher priced.

Not operational
The compass fell apart at 4 inches wide and I was unable to reassemble and remain together. Also, the pencil insert screw and nut as well as the metal stylus fell out multiple times. I spent a long time trying to male this item work but gave up in frustration.

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

Mala calidad
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!

Most reccomended for price
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.

Good value for a solid product.
Quality product, just what was needed. Versatile to use as can have lead in both points for marking swirls etc. Great for the design work it was ordered for.
