Review on 🔭 Bushnell Powerview Wide Angle Binocular: Top-quality Porro Prism Glass BK-7 for Enhanced Viewing by Joyce Brown

My first impression of them was pretty good. I was able to focus both eyes sharply on a bright star, collimation also seemed very good, and chromatic aberration was acceptable. (Note that this was just the case when I was pressing against a solid object; a tripod could have made subtle imperfections more visible). The next day I tried to see objects up close in daylight. Here, too, I was initially very impressed. Then, while focusing the binoculars back and forth, I heard a crackling noise and finally noticed an intermittent clanking sound (like metal on glass) as I moved the binoculars. I traced the sound to the right barrel and shone the flashlight into the lens. While I couldn't see the loose element, I could see a bunch of clear flakes sitting on the lens and scattered down the right barrel. I don't know if it was lens glue or real glass, but it's no good. I can't say what happened in transit but it was never roughed up or dropped into my possession. The only "shock" he could get was heat stroke from going outside to stargaze in 20 degrees, which hopefully shouldn't cause the optical train to collapse!
