Works as it should. Sturdy build.

Cheap made. Not as pictured on website. Contacted Amazon but as usual no reply.

This is definitely worth the money. The quality of it is amazing. The functionality of it is also really good. I have never used one before, but this one is really easy to use in the accuracy of it is excellent. Definitely worth the money and would recommend to someone else who’s in a search of one.

nice item fast delivert, thank you

This is an OK compass for a hobbyist or for somebody driving in a car, trying to find out which way North is. It looks very impressive and has many features, but it is not really a professional instrument. I took a closer look at mine and it turned out that the bullseye is not horizontal with respect to the base. Also, the top ring is eccentric with respect to the windrose, and this leads to up to around 3 degrees of error when you read the angle. If you really want to use this as a sighting compass and measure e.g. the width of a river, then you will have to make several readings and these errors will start compounding in your calculation. Also, the main issue is that a sighting compass should make it possible for the user to hold it horizontally, look at a remote object horizontally and then look down at the windrose to read the angle, all of this without moving the compass. No matter how I turn and hold this device, I cannot do it. I cannot get everything to line up at the same time. I looked at a US Army sighting compass, that makes this possible. If you want an accurate instrument, you might be better off buying that.
