Summary: This product is not worth the price tag. For comparisons I have Bushnell 10x25 (more than 4 yrs old) which is similar in specs but less than half the price. The olympus doesn't perform any better on the optics. The olympus is brighter (maybe because it's brand new) but there is visible chromatic aberration on the left lens (tested against moon at night). And on sharpness they both performs similar.
