The product arrived in plenty of time after ordering. The case that it was shipped in is a very robust pelican type case that is very durable and is great protection for the product. The contents were fully intact and well protected. Upon opening the case, I was disappointed that there were no product description/operating instructions. Even military systems like this come with operating instructions. I had to go to the product website to download instructions. Once I had downloaded the operating instructions, it was fairly simple to get the device up and running once the batteries were charged. After loading the mini card to set up the device, it was just a matter of going through the different operating modes and set them all up. This was not a bad process. 1. The daylight mode was decent, as one would expect. I did notice a bit of lag while moving the device from at a medium motion side to side. Upon mounting it to my m4, (I also purchased the mount), the picatinny rails fit nicely with no excessive movement. We fired 5 rounds and observed there was just a bit of “bounce or jarring”, probably due to the recoil of the rifle. 2. During dusk and night operations the device, (aurora), was able to easily acquire targets at 100yds. Again, the “bounce” was noticed during firing. At complete darkness, a scintillating effect was notice even after adjusting the forward and aft focusing features. A scintillating sight picture was observed at 100yds. This was cleared up much better with an IR light. When using an IR light/laser device we observed that there was a loss of the color feature of the device. We used streamlight and surefire IR laser/light systems. It was observed that we were not as accurate at 100yds while using the device at full darkness. Synopsis: The device is worth the price but it does have a learning curve to properly use it. The fact that there are no operating instructions when it was received is disappointing. The company is not very specific on the ability to attach this to a helmet or a headband device. All and all this device will work for individuals looking to acquire a good night vision device.
