I chose these because of the optics, BAK-4, multi-coated, etc. And they may be great, but I rejected them out of the box because the other design considerations were lacking. The neck cord is a shoestring and there are no "handles" to attach a comfortable strap. The weight "feels" a lot heavier than the specification. Comparing these to my old porro-prism Bushnells, I think the porros are more compact. Definitely lighter. I'll be re-ordering something along those lines.
