I used a Silva Ranger for over 20 years before it went off. Replaced it with another, did not last; you could tell that quality had slipped before even using it. It proved to be unreliable, so I got a Brunton Type 15 which has been solid for about 10-12 years now if I recall correctly. The bezel is a little stiff and harder to set precisely, but it stays put once set. No more Silvas for me. Of course, at my age I probably won't wear out the Brunton I've got.
