Compass for Geometry Large, Professional Drawing Compass Metal Drafting Compass Kit with Extension Bar,Metal Compass Geometry Set for Geometry, Drafting, Math, Drawing, for Engineer and Mathematician

I use this set for elements of iconography paintings. I am very impressed with the quality and accuracy for the price. In my opinion this set is well worth the price. I asked my husband, who is an engineer, what his opinion was of this set and he agreed with my assessment.

The device does what I need it to do. I was able to use my own pen by using the attachment that it came with. No need to buy the special ink that they recommend. However, I might look into it in the future.

I got this to draw circles on cymbals to cut them smaller to get rid of cracks. These are fine on paper if you clamp them down. The legs can bend in other directions while you spin the compass if you do not clamp them down. I'm not sure if I was missing some of the screws because I only have enough to clamp down one compass or the other, but not both. It's nice that it comes with extra metal heads and lead. I'm sure I'll use it for some craft that I need to draw circles for, I just wasn't able to get a consistent circle on an irregular surface. Maybe if it were a little more sturdy it would have. They tried to make it so it could be used in many different types of situations, but that caused it to be less sturdy because the legs can wobble while moving if not really tightened down.

First the item came broken open & broken into pieces. They sent a replacement which wasn’t broken. But the quality of the compass is terrible. It wiggles too much & comes loose easily.

Not professional quality, but what can one expect when there are no professional analog drafters and most stuff comes from the PRC? The parts work well enough for general use, but do not have the weight nor precise rigidity that someone who used this type of equipment professionally would expect.

Purchased as a gift. Have not received any complaints on the operation yet. I’ll let you know if I have any. To me it sounds like a good product I purchased.

I bought this for my son for his 8th grade math. It has everything he needs for this year and extra pieces that will carry him through high school. All of the pieces are sturdy and well made.

When mine showed up the small screws were off the tools and in the packaging.. luckily I found four of the five missing and used eyeglasses repair kit for missing screw. Tools work well

Soy estudiante de arquitectura y me sirve a la perfección, muy completo y de excelente calidad

the leg of the tall compass move all the time I tide also use plyer. It look good but that is all, I will not buy that item again.

Pésima calidad. Son una PORQUERÍA de productos. las patas del compás se abren de la parte media, y los tornillos que traen para apretarlos, no funcionan. La punta del tiralíneas están cerradas totalmente y chuecas. No coinciden en el paralelismo y la tinta se tira y mancha los trabajos. NO COMPREN ESTE PRODUCTO. Desafortunadamente lo empecé a usar después del periodo de devolución, así que tiré 499 pesos.

Je souhaitais utiliser cet ensemble pour faire l'esquisse de mes aquarelles. Seulement, avant même d'ouvrir le boîtier, on pouvait voir que les pièces étaient défaites: les vis et les écrous étaient éparpillées dans le boîtier. Le seul morceau qui était intact ne garde pas la distance choisi pour le tracé du cercle. Il s'ouvre et se ferme malgré mon effort pour ne pas y mettre de pression.

Es de buena calidad y cumple su función.
