I bought 10x42 for my mom. My first impression was good especially for the $250 price. Now she's had them for more than a year and I just saw them. I didn't spend a lot of time behind them on last weeks trip, but the eye ups weren't holding position. The durability seemed to be lacking, they just didn't feels as good as new. Maybe my mom doesn't take the best care, maybe she needs to send them in for service to test out the warranty service. I'm going to get her a lens pen and some cleaning tips, maybe that will help.
The case, lens, and objective covers were poor quality. I'm comfortable recommending the optical performance,but not the durability and quality of accessories.
