Review on 📏 Enhanced ZOTA Measurement Positioning Aperture by Ryan Gillett

Locking mechanism could be (much) better. The device does a great job if you manage to move it without touching it.

So you really have to hold your breath and move it around on a hot summer day like it's your plasticine baby to keep it shape.
