Do not buy. Documentation is inadequate, incorrect, or both. It was clearly written by someone with very little knowledge of English. When setting up something like this, you typically connect a network cable to your computer and device and navigate to the IP address to set it up. In this case, the instructions said to set up an IP address of 192.168.188.x on your computer and navigate to the device (there never really was the device's IP address), so I tried 192.168.188.1 and 192.168 .188.253 (the last address was on the picture in the so-called documentation). None of them worked. Internet research suggested that I should try 192.168.2.1, which didn't work either. So obviously they expected us to figure out how to set it up. I spent 3 hours trying to figure it out with no success. So I returned it.
