Bests & Worsts Reviews from Amazon

I purchased this to replace the Arris 1670 series modem I was leasing from Time Warner. I just wanted to save on the high modem leasing fees, but when I plugged it in and activated it, I noticed a 50% increase in download and 150% increase in upload speed. I had tested my speed immediately before and after installing it. My download speeds immediately went from 102Mbps to 154Mbps (download) and 9.8 Mbps to 25.6 Mbps (upload). I don't often take the time to leave reviews on products, but I felt this product warranted it.
