After reading several monoculars reviews, I decided to go with a more expensive product because of the reviews and I wanted a much better quality product.Out of the box, this monocular and included smartphone adapter is very easy to figure out how to use (but instructions were included just in case).The only thing I would suggest that the company adds to this product is an attachment string/cord for the occular (eyepiece) lens cover so it doesn't get lost. The objective lens cover is connected to the monocular.I am happy with this product so far and can't wait to have the opportunity to really use it.I attached 4 pictures to show just how it worked out for me. Keep in mind that these pictures were immediately taken after I opened the product to use for the first time. So I'm sure after practice, the results will be even better.(Photos taken with an iPhone 7)First Picture: Cell phone only with screen zoomed all the way out (phone default setting).Second Picture: Cell phone attached to the monocular with phone screen zoomed all the way out.Third Picture: Cell phone only with screen zoomed all the way in.Fourth Picture: Cell phone attached to monocular with cell phone screen zoomed all the way in.
