Helix 10cm/360 Degree Angle Measure (2)

Does exactly as it should, clear graduations, the moveable arm is easily detached if desired, and not warped in any way, like the first (Chinese) ones I bought. Buy good stuff, and you only buy it once.

Went missing in the post but when sent a replacement I was very pleased with the quality. Daughter loves using the full 360.

Great product, but why do I need two? Otherwise great.

Perfect for my application as I am designing a 10 metre diameter geodesic dome called Home in a Dome

All good
