An incredible amount of value for your money; must be adjusted if necessary

I bought this pair of binoculars from an Amazon partner for incredible 70. Goods was excellent re-use as-practical: So a return. I reckoned that the glass was out of adjustment, this is a common problem (especially from the reviews from amazon.com recognizable). The glass has adjustment screws, so I ordered it. Returning would have been possible.
It was exactly as I expected: The packaging was damaged, so a returns. The glass squinted extreme.
Adjustment is easy. There are two misalignments: 1) The photos are not the same high 2) The glass squints inwards or outwards. 1) is very disturbing, 2) like the eye of most. I describe here how to wegjustiert 1).
Under the rubber cover of the prism is an adjusting screw on each side: the top, to the eyepiece to, pretty much in the middle. Just the rubber with a precision screwdriver Raise, he is not stuck there. Then added the glass on a tripod (with the supplied adapter is almost useless), provides a possible distant destination (mast, Spire) and provides both eyepieces sharp. Then you look from a short distance, so about 15 cm into the eyepieces and shows a detail in one of the sides in the middle. By this view, the eye is deterred, to adapt to the oblique images. One can see very accurately whether an image is higher than the other. This one brings now with the adjustment screws for cover. That's it most.
On the inside, the center wheel out there are more bolts that balance the squint. But that is not so important.

Now the quality (of the adjusted glass): I want to use the instrument for astronomy, but it is also thought. A lightweight 15x70 is the largest glass on whose hands-free use you can still think. Peaceful images you get at this magnification only by applying all tricks, lean head, arms or elbows supported, etc. But you get halfway peaceful images without a tripod out, anyway, I. The Celesstron instrument is incredibly easy, my 20x80 weighs almost twice as much. When it touches the front and use of every opportunity you can really use it freehand. The instrument has Weitwinkelokulare and facing sheet 4,4 ° field. Exactly I have not measured, but just about right there. So you can have a lot of sky simultaneously in view, the prospect is a cinch.
The focus in the center of the field is sufficient. Of course, a 10- or 20-times more expensive glass is a little sharper, but large aberrations I could not tell. Blausäume high-contrast edges are just now visible and hardly disturb. The stray light rejection is reasonable (but not exquisite, because you have to go to other regions price).
Also for the unreduced a truly practice-oriented device, which you can take with you anywhere. Brand glasses this opening are so expensive that you would ever have fear of damage or theft. The restrictions that you have to accept it, are surprisingly low.
However, I was only four points, because
a) you could adjust the glasses factory
b) the tripod adapter is useless. Fortunately, the port has a standard thread, so you can use other brands. The 20x80 fit my example
Addendum after some time use: I have poured out the cavities of the tripod adapter with two-component adhesive (epoxy). The stiffness has considerably increased and it is useful. My advice to this modification.
