Review on Syncwire USB to Ethernet Adapter - High-Speed USB 3.0 to RJ45 Gigabit Ethernet Adapter 10/100/1000Mbps - Compatible with Windows Mac OS Linux - for Desktop Laptop MacBook Chromebook Notebook Surface Pro PC - Black by Mark Powell

I have to comment because I have a comparison. I had a TR unit and before switching to the new sync cable I checked the bandwidth speed and it averaged 146Mbps but the sweep was high to low everywhere. When I just changed the device, I could immediately tell that this new one is much better. So I checked the range and it ran from 200 to 200.50 but it was a flat sweep and the unit doesn't get hot like my other one and it has a little green and yellow light which I rely on. So folks, you can't get anything better than this block. I am very satisfied with this product, the cost of which is well above what I paid for it. Thank you Syncwire! It didn't take long before it stopped working, they immediately sent me a replacement and after a couple of weeks it also dropped from 800Mbps to under 60Mbps. My Rj45 gives me a solid 100 so I stopped using it. It was fun while it lasted
