I purchased these some time ago to take to Yellowstone NP and they did a good job. I used them on occasion to view stars while at home or check out red birds in the trees. They have been stored on my shelf for about a year and was packing to go to Alaska and took them outside to test. I found that focus on the right side could not be achieved. Also, the views were off on each side not lining up. I guess if I dont mind just looking through one side im ok, i take very good care of my things, i own a Meade LX10 Telescope for years and it works flawlessly, the one thing i would have thought would never be an issue would be the binoculars, never dropped, just stored on my shelf in the case....what a shame.
