Excerpt: These give a very nice, immersive view. They're sharp, bright, and reasonably contrasty. They get four stars rather than five because the adjustable right eyepiece does not maintain proper focus when the main focus wheel is adjusted to a different distance. It must be readjusted each time.
Pros: Compact, Quality Lenses, Strong Construction
Summary: Haven't used it that much yet but I really like what I have seen (haha) so far. Pretty robust impression and good zoom. Some smaller things is that with my glasses, I having a hard time to get the whole view. But other than that, I'm pleased with it.
