I bought the 15x 70mm just before Christmas 2013 along with the Horizon 8115 tripod. The tripod is a perfect match for these bins and even when fully extended it is rock solid, I love the pillar height adjustment being on a ratchet.

The binoculars are heavy and very substantial, The focusing takes a bit of getting used to as it is individual for each eye, Also the inter pupil separation takes some fine tuning as it is a tight movement on the pivot, Which means once it is set, It won't move a millimetre. You can grab the body of the bins to slew around without fear of losing it. In use the optics are amazing, Objects really do snap into focus with no fuzzy halo around even the brightest object,

As for eye relief, Well.. That's a slight problem for me as I wear glasses, I wish it was slightly longer, I believe it is around 15-17mm, But that's a guestimate, Fortunately I have a pair of flat lens glasses so can use these bins properly. Do check you can use these with glasses on.

I have also used them with my glasses off and in daylight they work brilliantly, At night I do loose some detail on Jupiter and the moons are fuzzy as you would expect with astigmatism, On the moon it's still crisp across a good 80% of the fov.

I have also made some solar filters using embroidery hoops and Baader solar film, The view of sol is impressive using both eyes.

I would thoroughly recommend these binoculars to anyone with any interest in Astronomy or not, Just be aware of the mid range eye relief.
