poor performance on higher magnifications


Focus was good at low magnifications but at the upper limit of X30 I could not get the left and right eyes to focus together. Also, there seemed to be a columination problem at X30 where the left and right sides were looking at two different targets....

Great for star gazing


Once set for my eyes the glasses have proven terrific for scenery and star gazing. The zoom function doesn't work very well for me, otherwise great bit of kit. The 10x magnification is too unstable for the races.

Too heavy and a bit awkward


Bit too heavy for me and a little awkward. Could not get comfortable with them so took them back and swapped them for a lighter set from Nikon. Not for me I'm afraid.
