The deal started off as a mix up in delivery . How ever once contacted the seller systematically stayed with me till the original order (the monocular) arrived . Hence , disappointed and tensed to start with but impressed and very pleased when it arrived .The product is really a fine piece of engineering . Having used binoculars before still getting the hang of it (need both hands to focus which at times is time consuming). As far as quality goes I'm quite dazzled as I have never owned any thing like this before . Compared to a Nikon 25x10 and an Olympus 25x8(I think) this is really fabulous . Like to mention the low light imaging , hard to believe ! If I manage to get as comfortable with it as I do a binocular I'm definitely giving it a five other wise it's human folly .
