80x100 Monocular-Telescope

To be clear -- no pun intended -- I didn't expect Zeiss optics here, but this thing is pretty bad. You know the old saying "You get what you pay for?" That rings especially true with this supposed "High Quality" monocular. I suppose quality is in the eye of the beholder. As another reviewer mentioned, the ratings are grossly inaccurate. I measured the objective lens with a digital caliper (yeah, I know, even the most basic ruler would have more than sufficed but I'm me), and it is supposedly 100 (that's in millimeters, folks) but as you can see in my photo, it only measures slightly over 41mm. Then there's the ridiculously overstated zoom power of 80. Really? 80?!? Naw, this thing is more like 8x, and that's a stretch. Then there is the optics "quality." Basically, you get a decently clear image in the center, say 1/2 of the field of view. Outside of that, the remaining 1/2 is blurry. Strike 2. I tried to get the cell phone adapter to work with my iPhone 15 Pro Max, but that was an exercise in futility. I could never get any of the 3 cameras to line up and get an image through the monocular lens. Strike 3, aaaaannnd it's going back. If you could get this for around $15, and it was intended for an 8-10 year old kid, it would be alright. Or for something to throw in the glovebox of your side-by-side. Otherwise, don't waste your money.
