I used mine several times this year and also at dusk, for the price they are a bargain.
The illumination dims down enough at dusk to not cause any problems. Just last week I was watching a buck all the way until dark enough I couldn't see him with my eyes but I could see him and his horns through the scope. With the illuminated dot I could place on the vitals . This is the first scope I've used with illumination and does a good job.
