The design is sturdy, and the rubber coating on the main body makes it very comfortable to hold. The central focus wheel is easy to reach and operate.

The focus wheel, barrel adjustments and dioptic adjustment are smooth and have a constant resistance. However, the dioptic adjustment on the right eyepiece has narrow limits, so if you have eyes with a large (greater than 2 diopters) difference in strength between them there may be some eye strain. The rubber hoods over the eyepieces fold back to allow glasses wearers to get their eyes closer to the lens.

I could detect no twisting between the barrels, or rocking motion of the eyepieces.

I was disappointed that the case which it came with was made out of a soft plastic, and not rigid which would offer more protection against occasional knocks and bumps. The case has no strap, although the strap from the binoculars can be threaded through the sides of the case opening.

The exit pupil diameter is large, with only slight blockage from the prisms which is not noticeable unless you look for it.

The field of view is wide and bright, with no discernible distortion of the image across the lenses. I did notice some chromatic aberration which is most marked when viewing sharp edges against a bright background. However, this effect occurs from less than half the field of view from the edge of the lens.
