I used this to draw lines 120 degrees relative to each other for a round table. It turned out great and was easy to use.

This was perfect for a mapping assignment. The markings are dark enough to read but no so opaque that you can't see the paper below it. It came quickly and the company reached out to ensure quality soon after projected delivery. I would definitely recommend.

I use this to create small and large circles by hand with a pencil. Easy to use with large enough print to read and is great for the price. Helix has always been a reliable brand at the right price.

As a Maintenance Mechanic sometimes I have to perform pump maintenance. So I have to cap off pipes while the pump is removed for a rebuild. The bolt holes on the cap must match the bolt pattern on the pipes. This 360° protractor helps me draw out bolt hole patters accurately!

Absolutely the most confusing tool I have ever used. Even my daughter’s math teacher couldn’t figure it out. It’s going in the trash.

Bought this for dividing up circles in equal and unequal parts like in pie charts. Saves a lot of guesswork.

This was my fault for not looking at the product picture closely enough, but the 0-360deg marks are CW positive from the +x-axis; the opposite from standard angle measurements in nearly all engineering and physics coordinate systems. The construction was otherwise solid. It would have been nice if the 5deg ticks were slightly longer to make it easier to get a measurement at a glance.

Seems like a nice protractor. The markings are distinct and the thickness adequate to keep it from cracking with reasonable use. There were no injection molding spurs on any of the edges which pleased me. It comes in a clear flexible protective envelope.

Ho acquistato questo goniometro perché necessitavo di una più precisa scala graduata ( 0.5º). Ma purtroppo, superati i 90 gradi , ho riscontrato delle evidenti imprecisioni. Spero si tratti di un caso isolato di difetto di fabbrica. Se così non fosse, nn lo consiglio.

This little guy is really handy and better than a regular protractor in my opinion. It's nice not always having to do the math in your head when dealing with angles greater than 180 degrees. The product itself is really sturdy and it has survived being lose in my backpack for an entire success.
