I have a pair of Zen-Rays ED2 also. And a pair of Carsons 3D Both 10x42. Hard to beat for the $s. I will say the twist up eye cups are kinda cheap. But Ive also seen that with a lot of so called name brand glass. Been extremely happy with both. And they get some pretty rough use. Had both sets in for eye cup repair on warranty. Service was awesome on both!
