This is an expensive bit of kit - especially in combination with the 95mm objective lens module, but once you've adjusted the eyepieces to your own physical needs, the view is amazing. Bright and crystal clear. On a sunny day, the views are jaw-dropping. Magnifying 35 times and focusing down to 5 metres (with this objective), you can fill your field of view with a small bird. Focusing is critical, but accurate, and the three-dimensional effect obtained is stunning. One of the best purchases I've ever made.
Would have been nice if the binocular eyepiece could have been used on other lenses - like my 600mm Canon camera lens. But I guess that sort of compatibility would have negatively impacted the design practicalities of this modular system.

As an eyepiece for fixed viewing, it is excellent.
Bit heavy to move around. doesn't really matter to me as it will be permanently set up for viewing from a living room with a 180 degree view.
