Review on 🧭 Waterproof Military Metal Sighting Navigation Compass with Inclinometer for Hiking, Camping, and Boy Scouts - Impact Resistant Multifunctional Compass by Alex Jain

I have a few comments about this product: 1- There is a midget instruction, and it is not written clearly. To understand this, it pays to get a PhD in physics. 2- Building materials are not of very good quality. 3- The lid can't keep 90 degrees stably; The hinge pins have zero friction to keep them in place. 4- There is no way to align the line of sight with the compass guide line, there are several degrees of error. 5- The moving part of the inclinometer sticks in several places, so the metal wall of the backrest appears to be magnetized.
