My first impression of the Zhumell 10-25x 42 monocular is favorable. Optical clarity it's not anything special as sport optics go but the optical clarity is functional and at current market prices this scope is priced about right at U.S. $50-60. This is a very powerful little monocular that's perfect for those harsh environments where you don't want to put more expensive optics at risk. As a reference to optical quality, I was able to read a car's license plate number at a measured 275 yards. I was also able to read the print on my drivers license at 40 feet.
The objective lens optical coating is actually blue/green rather than the red shown in the promotional photo's. Colors as seen through the monocular appear correct. The focus and zoom adjustments are stiff enough to hold their settings. The focus adjustment moves smoothly but adjusting best focus at higher magnification takes patience. The rubberized outer coating feels secure in your hands. The monocular is equipped with a metal ¼ -20 threaded hole for securing it to a camera tripod or monopod. Close focus distance at 25x is less than 3 feet. Eye relief is comfortable for people who don't wear glasses but probably not fully functional for people who do wear glasses/sunglasses while looking through this monocular.
