This product offers a good price / quality ratio.
It comes in a box that curiously ad binocular (???). It is a product with a manual in Chinese (but super simple to use). It smells very strong rubber but gives a solid feel. It comes with strap (plastic), cleaning cloth and cleaning pouch (with belt and pass scratch).
In use, I was a little surprised that he did not seem to offer me the announced capacity and for good reason: the measurement of lenses is their size before mounting but once installed the unit conceals a part of the lens which makes the final we have a usable portion that corresponds in reality to 15x39. However, this provides a sharp image up to over 250 meters.
The adjustment is made by turning rings: one on the front for the distance and the second to adjust the sharpness in the center of the unit. The exit lens is lightly tinted blue to avoid being dazzled.
It is not waterproof but resistant to rain and dust through caches. However caches do not take very well. Against by the plastic coating of the device is sturdy and will withstand it with water (not more than the rain).
I did a crash test which proved very convincing for the lenses but not for the output cache, the base has exploded as a fall over and ended with the weight of the unit that was not forgiven. The cache is still holding up so far and this says it still works fine and lenses are still in place.
Strengths:
_a sharp image
easy _réglages
_bonne robustness of lenses
Weak points:
_moins powerful announced
_caches ways and weak in the output cache, not properly secured to the input cache.
In conclusion, I would have 3.5 but can not I put 4 stars because for such a low price, it's hard to find fault since the image is very easy to adjust sharpness and the Product does his job. We see perfectly the details of more than 200 meters.
I said that this was sent to me for independent testing.
