The design is pleasing and professional. The optics are excellent, I took them to the store for a comparison with Vortex diamondbacks 10 x 42. They are slightly clearer and sharper than the Vortex brand. I took plenty of time to establish that, no question. But, the bushnell $50 cheaper price comes with secondary design flaws. The occular side rubber cup sleeves that your eyes rest on that are supposed to be a permanent part of the binocular are sliding off the hard barrels and one of mine has come off. It's easily put back on but there is a high risk of loosing it. This is likely to happen when you affix and remove the separate one part protective rubber duo caps. At the other end of the binoculars there is a similar problem with the objective lense rubber protective caps. They cleverly attach to the barrels hard chassis via their ring rubber extension. That too slides off and falls very easily for example if you take the binocular out of their soft carrying bag. These two things do not affect the optical performance at all. The vortex use hard plastic at the occular instead of rubber (which could be less comfortable) so does not have that issue. The objective rings is just an annoyance but if you loose the occular side rubber it exposes the eye relief guides grooves in the chassis which is more of a concern. After a coupe of days using them i realized the focusing wheel has slack in it. I went to a local store that has the E model with same mechanism and the focusing wheel was firm without play. This slow down the ability to focus every time you change the focus direction. I felt this a more serious defect that impaired usage direclty and decided to return them.EDIT: I got the replacement binocular. All the issues are gone, even the rubber rings seemed to be made of a more elastic rubber don't fall off. The focusing wheel is normal. Though when they arrive something looked wrong with the diopter locking ring which looked pushed down slanted but as i pushed it down i clicked fully and went back straight. After that I had no problem with it. For the price though these are awesome binoculars, again the optics are excellent better than Vortex diamondback and I used to own Talon Vortex as well at $380, though pin sharp in the center they were not as shap in the periphery of the field of view like the legend. My conclusion is that these are $400-$500 optics binoculars with mechanics no better than a $100 binocular. The result is an extremely appealing value. From the issues I had on the 1st pair only the loose focusing wheel was a performance issue. With the 2nd pair I am very satisfied. These are excelent binoculars for bird and criters watching. But I would not take them in the dirt. These are not military grade ruggedness in construction, it's all about the glass.
