I have a VX-6 with and one without the Fire-Dot.

The Leupold lifetime warranty does not apply to electronic parts. IIRC, that warranty is two years.

Hopefully if work is needed on electronic components, it won't be too expensive.

They did a good job with the dot. You can't tell it's there when turned off, looks just like a std. duplex. You can adjust the brightness and the thing shuts down with non movement to preserve battery power. It lights up when you pick up the gun, triggered by motion. Pretty neat.
