Mr. Pen- Professional Metal Compass Set, 7 pcs

1. Was concerned when I read some reviews that said some screws were stripped. Actually they are NOT stripped, but free wheeling. In order to tighten, place a finger on the UNDERSIDE of the screw when tightening. Problem solved 2. I was concerned when I read that the protractor "wobbled" when the extension was attached. Only if it is NOT fully inserted into the slot and SECURED by the screw, If the screw is not secured by the above method, then it will wobble, otherwise NO problem. Works like a charm! 3. Only complaint is NOT enough information provided by the supplier. The "cute" included mustache isn't so cute when you have to solve the problems yourself and the "cute" video FAILS !

I needed a reliable divider for a U.S. Coast Guard Charting/Navigation Course, and this tool did the trick. Super sturdy, reliable (in a classroom situation), and seems like it would be pretty durable (in a non-saltwater environment). The price and quick Prime shipping is what set Mr. Pen apart from their higher priced competitors, so I took a chance, and I’m glad I did. Definitely a great balance between price and value — I recommend this product. :)

My initial impressions are very good. It is a substantial feeling compass, good weight to it and the adjustment wheel is very sturdy. Overall I love the feel of the device and think it’s going to meet my needs for a long time to come. For the money I certainly can’t complain. If there were any complaints to be had, there was a little trouble with removing and installing the attachments for the extension, not sure why but I ended up having to take the set pin completely out, not a big deal. There is also just a slight bit of play in the joint where the arms meet the at the legs. This was easy to deal with and I don’t think it will be a deal breaker. I love that it came with spare parts and additional leads. I also like that it came with an attachment for a regular pencil. Overall very happy with the purchase!

This thing is way beyond what I expected! I needed a compass that made a10" circle for a mask pattern I wanted to try. The first one I bought, the description said 9". Not really what I was looking for, but I also didn't want to pay a lot, as I might use it once, not like the pattern, and never use it again The description said 9", the packaging said 8", and it only open enough to make a 7" circle. I contacted the seller, as they asked in the packaging. They immediately refunded my money. But I still needed a compass. I found one that said it made a 10" circle and had a video. It was from the same company as the one I'd just had refunded, so I felt safe giving them another shot. Wow. This thing. I'm not a professional... anything, but this compass is definitely professional quality. It's got some actual heft to it. It is just way beyond what I was expecting. Plus, it cost less than the others that claimed to be what I was looking for. I would recommend this to anyone who needed a compass, large or small. And you can't beat the customer service!!

Update: I contacted the seller and his response was super fast and sorted out the problem right away. We now have a compass that works well and that one must have been a one off one that has a problem. My son loves it and the feature where you push both bottoms to expand it quickly is super useful when he is doing his geometry homework. That way, he doesn’t have waste time using the small dial to expand the leg or reduce the size. ————- (Old review) I was excited to get this for my son for his Geometry class. So was he. All are great such as refills, extra screws, the little metal plate as a screw driver to tighten the screw for the leg that bends, additional leg to draw a big circle (although this isn't necessary for his class), but one slight oversight which is annoying to use is the screw that tightens the legs from bending. The screw head is so shallow, I cannot tighten it before threading the screw. Needless to say that I cannot tighten it. So, when my son uses it, it kept bending when he's putting his point down on the paper firmly so that the compass won't slip off. I told him to grab the bottom part of the leg while he is pushing down on it. Contemplating on returning it and see if we can get the proper one to tighten the legs. But the inconvenience of it... sigh... If they could just replace the screw (if that screw can be replaced), that would be perfect. All other features function fine and would have been a great compass with 5 stars.

I wanted to give more stars, but the main reason I purchased this compass was for the beam attachment. Unfortunately, the beam just does not provide the stability and accuracy I require for my art. However, the compass without the beam is very nice and pretty sturdy. This compass is the best in it's class for price. There are many like it here on amazon and art stores all over. Most are really cheaply made and over priced. For $10, this is a deal. Also, I have to use pliers to tighten for accuracy. I will continue using this compass for my drawings that are under 14 inch diameter.

This compass set should not be on the market for sale! There are so many flaws and problems with this thing that I have a hard time finding a starting point to describe them. First of all, nothing was secured in the thin transparent product box, and everything was loose clanging against each other and rattling with the sound of metal and plastic banging around. The thin plastic product box itself was torn in different places, and the compass had banged around inside the box so much that its needle and lead points had lodged themselves into the bottom of the box and sticking out of the bottom of the box a good three eighths of an inch. Beyond this, the compass which is made of plastic at the top (the handle and the plate covering the arm hinges) isn't even straight. In other words, the handle which is supposed to be aligned with the arms is actually at an angle against the arms. And the adjustment screw rod is not horizontal, meaning that the screw holes in the two arms aren't lined up properly. The components such as the pen/pencil adapter and the technical drawing pen handle are made of incredibly cheap plastic. I never opened the box, because this piece of garbage is going back immediately. I could see all the deficiencies through the transparent plastic box's cover and thankfully didn't even have to open the box to observe the problems with this disaster of a product. Just don't waste your money on this compass. Seriously, I wouldn't take it if they gave it to me for free; it's that bad.

I had previously ordered a different compass here on Amazon, and it was absolutely terrible. Thumb screws that were too tiny and were plastic, so if you tighten them just a little bit too much they broke. No well-defined channels for the lead or point to sit in, so centering them was impossible, making the setup process a total exercise in frustration. I went back to Amazon to find something better, and thought I'd give Mr. Pen a try. Well, the mail just got here about an hour ago, and there it was - my new Mr. Pen compass! The clouds parted and the sun shone down! I love you Mr. Pen! Please don't tell my husband! I couldn't be happier with this compass! Solid construction - it's got some weight to it, but not too much. Clearly defined channels for the lead and the metal point - they just sit right in there and are ready to go. Thumb screws that are the right size to not make you feel like your hands are ridiculously large, and the button release levers for adjustments are magical - no turning the wheel for hours to change from a tiny circle to a large one! The extension arm has a widely adjustable pencil holder that you can fit pretty much any writing implement in - even a Sharpie. And to top it all off - a mustache decal! I couldn't be happier with my new Mr. Pen compass!! Thanks for making my day, Mr. Pen :-)

Muy bueno, estudio arquitectura y me ha funcionado para todo

Solid purchase.

あちこち曲がってたり、作りが雑で使いもんになんねー

Problem with many compasses is that the radius can vary during use, with the slightest bump, or uneven pressure when drawing. The Mr Pen compass is sturdy, has a sharp point and almost every movable piece can be easily secured by tightening the various screws. The only bits I couldn’t tighten, I immobilised with a little cellophane tape or electrical tape. I can now draw at least 20 circles with the same radius, without checking and readjusting the radius for each circular arc. If you’ve ever has trouble using the expensive brand-name compasses, you might be pleasantly surprised how the Mr Pen compass is *much* more reliable. I heartily recommend this compass. The only downside is the international freight cost which more than doubled the price - even with Amazon Prime - the cost is disguised in the cost of the compass, and not separately itemised. In the US, you’ll get one 1/3 of the price I paid.

it gives me more options when technical presion is needed
