Multiple purposes

This set it great. Easy to use, portable and It comes with a lot for the price. I gifted this to my man and he loved it. It also comes with a lifetime warranty which is a plus! Highly recommend

Great product, minor defect but was quick to resolve

Great product. The numbering increments are clear and easy to read. The set that I received did have a few manufacturing defects (possibly a bad batch) on a couple of the plastic surfaces but Mr. Pen support was super quick to respond and resolve at no cost so I still gave the 5 Stars. All of mechanical parts work great and have a very smooth action and I like all of the accessories that come with this kit.

Bad compass

The overall set is good but there is a design flaw with the compasses, the one with the twisting had a design flaw where if you open it too much, it becomes loose and hard to draw, the other compasses open too easily and shifts midway through when drawing an arc, the mechanical pencil is kind of bad because the lead doesn’t really work, the protractor asl so has a design flaw where you can’t draw the full ray, it was pretty easy to use. It’s very portable and durable and easy to organize as it comes in premade holes

Good Basic Set for the Price

This is a decent geometry set for the price. The compass works fine for basic use, and the included tools are helpful for school or simple projects. Not the highest quality, but definitely good enough for everyday tasks. Overall, a solid budget-friendly option.

More than adequate.

A variety of compasses and protractors. The swing arm is designed to take a pen or pencil as opposed to a simple lead. One quibble. The pivot for the compass swing arm is about 1/8th inch above the horizontal. Putting the vertex at a particular spot requires moving the compass slightly without rotating it.

Quality stuff, inexpensive.

Not durable by functional.

Great for trig, smooth to use, but one drop and it’ll fall apart/break. Not durable but functional
