Review on 📏 Precision Deluxe Caliper by Airgoesin: Optimal Measuring Accuracy by Justin Guldin

I was looking for a more durable caliper that would be easy to carry in my pocket. I like the design, but the workmanship leaves a lot to be desired. At least the rubber o-ring seems to be too big, which prevents the two parts from connecting easily. The calipers are not snug against the cover, so force is required to push them out. This intern makes it difficult to remove them for use. The movement of the caliper is not smooth, making it difficult to get consistent measurements.
