Eyeskey10x42 Professional Waterproof Binoculars, Best Choice for Travelling, Hunting, Sports Games and Outdoor Activities, Extremely Clear and Bright

I had purchased the Eyeskey 10x42 professional waterproof binoculars as I wanted something to magnify a bit more than my 8x binoculars and small enough with which to backpack. The Eyeskey might be well made but I couldn't get a field of view that combined well the view from the right and left components. The focus adjust knob was quite tight and not smooth in its adjusting. By the time I got it adjusted, any bird at which I was looking would disappear. There was also a small circle in the field of view that made the image odd. It was most noticeable when viewing branches with sky behind.I am in the process of returning for a refund. These 10x42 binocs might be more appropriate for someone who doesn't wear glasses or with eyes that are farther apart than mine, or younger than mine. I may have been spoiled by binocs with quite large objective lenses. I have pairs that are 8x56 and 15x70 procured years ago for astronomy.

This is the first pair of binoculars I've owned. Did a fair amount of research on different brands/models on Amazon. Finally settled on these (8x42). Glad I did. I've only used them a few times so far, but I can tell these are well-made with quality components: the way the binoculars feel in your hand, the materials, the way the focus knob feels when you rotate it...even the strap and carrying case are well-made. They even come in a nice box with well-written instructions. The optics are clear and bright. I'm no optics expert (and again, these are the first binos I've bought), but I doubt you'd be able to find lenses / optics any better than these at this price range. (I'd put these way up near the top of the list in the 'Best bang for your buck' category.) One note though - the interpupulliary distance on these is somewhat narrow, even when adjusted all the way out. It's fine for me, but if your eyes are especially far apart, you might have trouble with these. Bottom line though - if you are looking for a good pair of binoculars for around $100, look no further!!

Love them, lightweight, compact and easy to adjust to get a good clear view. Lens protection cups are easily attached to the binoculars and the strap for hanging them is long enough but not too long for a shorter person like myself. Also came with a cleaning cloth and good directions for adjusting the lens.

I ordered these to replace a broken set of compact binoculars, but these are much bigger and heavier than my old ones. For me, viewing is best with full-size binoculars, but at times you need something smaller. This set seems to fall in between. They're as quirky to use as other small ones, but still too big to conveniently carry in pockets on on your belt. Returned them and bought these instead: https://www.amazon.com/Bushnell-Waterproof-Compact-Prism-Binocular/dp/B007JNWCDE/ref=as_li_ss_tl?ie=UTF8&linkCode=sl1&tag=omibinoculars-20&linkId=843a7f2412453d1a7e126863f81213ea&language=en_US&th=1. Work much better for me.

This adapter works really well for securely attaching monoculars and binoculars (one side only) to the larger iPad Pro. It is about the only solution out there that I could find that reliably works with all sizes of mobile devices and a broad range of optics ocular diameters (where the ocular is unobstructed 360 degrees around its circumference). The lever-release suction cup is a champ and really holds tight / firmly on the back of the mobile device, and can support substantial weight on the optic hanging from it without ripping loose. It is important to understand, however, that it is best to use the suction cup on hard, smooth surfaces — so removing any decorative or protective cover will most likely be necessary before attaching the suction cup. I use a piece of clear packing tape as a makeshift cover to keep the section cup surface clean and free of oils and debris when the adapter is not in use. My only disappointment is not with the adapter, but learning how inferior the digital cameras are on my iPads compared to the cameras on my smaller mobile phone devices when hooking up optics — especially for low-light photography. The digital camera on the Samsung S9/S10 really pops (shines) when used with attached optics (scopes, etc.). This adapter is a solid “five stars” for what it does.
