I bought the device, because if the binoculars will be too faint, stop, an image intensifier is announced. The 5-fold magnification of this product is excellent, comparable devices have an increase of 2-3 times.
My +/- points:
-) The very brief instruction manual is silent on the water resistance. This on the one hand, the suitability for "boating" is touted, on the other hand it is not recommended to immerse the device in liquids, or even "to use cleaning fluids" only. In previous reviews I have to also found no evidence, apparently no one has thus been exposed to rain :-)
-) The lens cap is attached to the housing. Especially when it's dark, which is a fumbling, so as not to lose him. The controls are not exactly arranged ergonomically, which initially leads to fumbling in the dark, but that's matter of habit.
+) My device does not have a single "dead" pixels: In the instruction manual is mentioned that would on manufacture one or two pixels might not work, that would be no shortage. This reminds me of the early days of flat screens.
+) Both the resolution (after all, is not the "analog" appearance), and the (adjustable) light amplification and the magnification are very satisfied me.
I can not forgive, because there are no clear statements regarding water resistance, shame the fifth star.
