Offizeus Professional Geometry Compass with Extra Lead Refills

Djilly L.Djilly L.: We ordered this friendly-priced maths compass for our daughter who is entering secondary school. Bought this one as it lacks the cog-based mechanism that typically broke down in my math glory days decades ago. Therefore as I expected it should be somewhat sturdy and durable. Though we will have to see how well it will withstand a teenager's fidgeting hands and school bag transport. The compass comes in a thin soft plastic cover and is easy to take along. Some additional lead refills are provided as well.

Our daughter has already drawn perfectly round circles of all sizes with this compass, all the the full 360 degrees! Therefore I would recommend this compass to navigators, explorers, all sorts and illustrators and of course eager maths students.

J. Matthew: Able to draw perfect circles as long as only minimum pressure is applied, otherwise the point may get pushed in

Amazon Customer: Really poor quality and appeared a knock off fake. The blue plastic swivel which is meant to screw down to hold the open compass in place was actually a solid fixed fake piece that snapped off.

Old Nick: The compass is simple and is supplied complete with leads including spares in little tubes.

Having said that, the compass is excellent in use. The "legs" are held firmly in place making it easy to draw accurate circles and yet they easily adjusted. It was just what I wanted. I have need to draw many circles on wood and have bought several compasses including so called professional ones. They have all been a disaster! This one however is perfect. It is simple , sturdy and precise. It does what it says on the tin!

Momma Becky: I had a set that included a compass, but it didn't lock into place, so trying to teach a beginner how to hold it steady wasn't going very well. This one has the wheel to wind it out to where he needs it and it stays in place for him to use it without worrying about it sliding in or out. This one comes with extra lead and even a couple of extra screws and wheels, and it seems to be pretty sturdy. It's reasonably priced and good quality, so I'd recommend it.

Sóley K.: This is an excellent compass, definitely lives up to its claim of bring professional grade. Save for the lead (and the bottles the refills come in) the entire thing is made of metal and has a bit of heft to it. Sturdy enough for all kinds of projects!

I did take one point off of ‘easy to use’ because adjusting the compass is a bit awkward due to the placement. But it doesn’t lose any more than that because while it is difficult to adjust while in use, you definitely aren’t going to bump anything off course or accidentally move the arm a few degrees.

As a side note, shipping was very prompt and the product came in a little, clear, resealable pouch that I’ve chosen to keep for storage.

Anjali JAnjali J: This is a pretty neat compass if you don't mind making a modification to get the best out of it.

Pros:
- Cheap price for a metal compass - most at this price or even a little higher are plastic.
- Holds position really well - little to no movement once you have it set.
- Plenty of spare parts, especially for the price. This part impressed because I've seen compasses that cost three and four times the price that don't have so many spare leads and don't have any spare points or screws at all.

Cons:
Just one and it's a huge one; no matter how tight you make the screws, the legs are hollow and there is no stop for the lead or point, so even the slightest pressure causes one or both to slip up inside the legs, making it difficult to use if you've anything more than a very light touch. I ended up modifying mine by filling the upper section of the legs with pieces of an unused ice lolly stick which I taped in place. It's not pretty but it does the job until I can find a better looking solution.

J. Turner: The compass arrived today, and I put it through its paces--I found none of the problems that I read about in some other reviews. It is very sturdy; the point and the lead stay firmly in place; the screw to enlarge or compress the circle radius works smoothly; and it is easy to twirl around in making the circle. It also comes in a nice recloseable plastic carrier along with its many replacement leads. I would recommend this to all my geometry students and will probably use it as my personal go-to compass.

Shawn R. Malcolm: When ordering, I was skeptical about the quality because of the ultra reasonable price. Item arrived two days later. compas is straight forward to use; both the pointer tip and lead have adjustments. The main adjustment wheel is metal fine thread rod and wheel, allowing for finite radius adjustment. seller provides plenty of replacement lead and even a couple small adjustment wheels with screws. You dont realize how valuable a tiny screw or wheel is until you drop one and it falls into the shad carpet black hole. Highly recommend!

James M George Jr (jgmanage@aol.com): I'm using the compass mostly for drawing designs on wood for carving. This is a little more demanding than using on paper. It works, but does not have the strength that more expensive ones do. The graphite or stylus can slip, and if I'm not careful, the screw controlling the angle can be nudged accidentally, changing the setting - it doesn't lock. As I said though, it works, and is value priced.
