I was really looking forward to getting this monocular as it quite clearly states the two things I wanted: night vision, and smartphone adaptor.The “instructions”, take the form of a small piece of paper with barely anything useful printed on it.The 'scope itself is light, easily held in one hand, and easy to focus using the knurled wheel on the top, but I'm puzzled by the markings on the end of this: 211FT * 1000YDS. What does this mean? Is this the distance range? Why is one if feet and one in yards?It's not particularly well made, the covers on the lenses are sloppy and easily come adrift. The rubber ring which holds the large one in place is too big and quite stretchy, and although the smaller cap – the one for the eye piece, has a loop, presumably for attaching it to the 'scope, there is nothing to attach it to.What disappoints me most , though, is that this does not have night vision. I've had one or two family members test this to see if I've been going wrong somewhere, but no, definitely no night vision. Interestingly, the list which indicates what this can be sued for includes no night time activities, such as star gazing, which is what I wanted it for.The second disappointment is the plastic screw which should enable to smartphone connection is so badly deformed, it is rendered totally useless. There are no instructions for attaching this to the device, so – assuming you get one with a working screw, you'll just have to follow your nose.In conclusion this monocular can be used in the daytime without a smartphone and therefore provides only 50% of its claims, and as such is too expensive.
