Review on Monocular Telescope Smartphone Waterproof Travelling Camera & Photo by Logan Barela

Nice feeling, well-made telescopic sight. The zoom works well, helping you get close to subjects when needed, although don't expect the difference between 10x and 20x to be huge. Sharpness around the edges as I would expect given the price and unnamed brand. The main weakness of this scope is its low contrast, although it would be nice if it had a strap to attach the eyecup cover to the scope's strap mount. .
