Professional Geometry Set Metal Compass, 7 pcs, Geometry Precision Tool Set with Shatterproof Storage Box, Drafting Tools & Drafting Kits

Like it! But refillable lead is a pain, dulls quickly, breaks, must keep unscrewing to advance lead. Fortunately the Pencil holder attaches to larger compass and a slim mech. Pencil fits great, as shown in pic—that means advancing lead from end of pencil, no unscrewing, less interruption in drawing. For small compass w/ thick refillable lead, the sharpener is handy. Well worth the price, good quality!

this is a real quality instrument with a beam to increase the working radius. you may need to watch a video on how to use this, i do not have one.with this, you can do home remodeling to scale (architect ruler needed), home yard improvement/landscaping and many other things.comes in a good case, and i would give this as a gift if i had any friends (who would use it)

What you see is my attempt to use my Mr. Pen set. I was looking forward to this set because I wanted to start working with mandalas. My only experience was high school geometry and that was limited to the usual cheap compass that came in a school supply set.The cute little mustache print and thank you included did not make up for the lack of instructions. It does say a professional set, so maybe I should have looked for a beginner set to learn the mechanics.I attempted on my own, but there were pieces included I simply didn't have a clue about. Again, I'm not a professional with a compass.I can't tell you how many times I had to chase that small screw when it flew off its pin. (I'm left handed and sometimes get righty-lefty backwards.) That pin is tiny. Be careful you don't lose it, or the screw head.I didn't understand the extender at all, so I turned to online videos. Mr. Pen does have a video, but it moves quickly. His hands are in the way sometimes. Not all the things in my box were addressed, so I still don't know what one thing is. I did manage to see enough on the video to figure out the extender. After I removed it, I realized the pen/pencil will slide back and forth on the extender to make different size circles along with screwing the compass wider or more narrow. I'm sure that will be a nice feature after I become more adept.While I was chasing those tiny screws, I saw the random marks on my paper you can see in the photo. I was trying to fit the pencil holder on the smaller compass to no avail. However, in that process, I noticed I made more marks. Well, what do you know? I discovered there's lead on one side for both compasses, you don't actually need a pencil unless you are doing the really big circles from the extender.Again, it could be my lack of experience, but some simple written instructions and photo showing parts would have been helpful and less frustrating.As it is advertised as a professional set, I don't have anything critical to say. I'm a professional artist, not architect. I'm imagine that made a difference in my experience. It seems sturdy enough, especially for how I will be using it.Eventually, I did figure most of the bits and pieces out. One thing included is supposed to be a screwdriver (from the video), but it looks like it has a blade and you need a tiny screw drive to turn it. I thought it was some sort of sharpener until I watched the video. I will have to watch again to figure out where and how to use it.The other thing I am clueless about. I can't tell you what it is because I don't have a name for it. It wasn't addressed in the video. It appears to attach somewhere to something. I'm sure, eventually, I will get it figured out.My experience with the set, may not be typical, but if you are a beginner using such tools as I am, I hope this review will give you advance idea of what you may be up against while setting it all up.As to the photo. I used a not so great photo because I thought it would give you an idea of the sizes you can make. You will see the random marks I referenced in my review. I just used a sheet of practice pad to make the circles.As I use my rulers for artwork, they are clear. I knew nothing would show up in the photo. What you see is a seam measure for sewing, but it has inches and metric on it. I made as small a circle as I could with the smaller compass and then as large as I could. The arcs off to the right side were made with larger compass, the extender and a pencil. I did not have the larger compass extended as far as it would go, but I did have the pencil extender at full length. I didn't have large enough paper at hand to complete the biggest circle, but you can get an idea of how large a circle this set can make. You can go from 1/2 inch diameter up to very large dinner plate sized circles that might be good for murals, signs etc.Again, I think this set will be good for my purpose after I get better at using it, but instructions would have been so helpful.

This is working as expected and covers all requirements for kids to complete their work

Good price, the compass of good quality, a set for professionals. I can recommend it.

The media could not be loaded. *Edit* I would like to first say that the customer service is the best I’ve dealt with. The company does take great pride in their products and are not just sending cheaply made junk. If there’s a problem then they want to know and want to fix it. I hope the issues are addressed and I would definitely purchase from them again. I think I would avoid compasses that have plastic parts that are important components though.I knew at this price that it wouldn’t be made from the best materials or have precise, German like engineering. I was certain that it wouldn’t last for years or even a year at best. At the moment I couldn’t really budget in a high dollar compass so I decided on this one. I bought this around July 8th of 2022 and had immediate regrets.As shown in my video… the inserts that hold the thumbscrew are really loose. The thumbscrew is also loose at certain lengths which has to be adjusted regularly. I say regularly like I’ve had it for awhile but it’s been less than one month. It didn’t slowly start getting loose… it came loose and has progressively gotten worse. It probably wouldn’t be too bad if it wasn’t a precision instrument. Well it is a precision instrument and that means loose parts are a huge problem.It isn’t all bad though. The small compass seems to be kinda decent and would be good for something small, really small. I haven’t used the extension arm mainly because the big compass doesn’t really need more variables to throw everything off. Everything else is pretty basic. I’m always exited when there’s a free sticker and this one came with a mustache one. While that pleases my sticker collection, it’s not enough to gloss over the loose compass.There were a couple of other inconvenience like the lead wouldn’t come out so I could sharpen it. Even after removing the screw that hold it in… I still had to get a pick to get it out.I was excited about the pen attachment because I’ve usually just taped a marker or pen to one of the arms. This was going to be a game changer for inking my drawings. While it does well for pens, it was too small for a sharpie. When I say too small… I was able to force one in it but it took some real effort and a little sandpaper on the sharpie. If only the compass was this tight. There is also a plastic screw on the bottom of the attachment to angle the pen for some reason and it’s awkward to get to. It doesn’t really matter because it’s loose too which makes the compass even more inaccurate.Overall it’s just an unfortunate buy. I had relatively modest expectations but was disappointed when I realized I would have to make constant adjustments and still not get the precision I get from a cheap, flat style compass like I used when I was in school.
