Summary: Mine probably just had something wrong with them - they were still super helpful and I do really like them otherwise.
Pros: I was able to get a LAN connection upstairs in my house which was super awesome. Things run really well and are a breeze to set up.
Cons: Sometimes disconnects for me. Probably once every hour or so. It really hurts my experience playing games as the outage normally kicks me off of whatever game I'm playing. I often end up just going back to WiFi.
Excerpt: I chose the product for compatibility, since I already use a Linksys E2500 Wireless router. I plugged it and it played. I get internet access in the lower floor in the house, streaming Netflix without a hiccup.
Summary: Works most of the time. the signal will drop fairly regularly but then come back. The data throughput rate is slower than expected - though I suspect that's because of where I have the devices.
Summary: Unbelievable and so easy to use too. Tried a wiFi extender to reach my Roku (Across the house from Verizon Fios router) Still not enough to stream any video without constant buffering. Plugged these puppies in and great wired connection.
Summary: 1. The mac address & password label have been removed. 2. The bandwidth is extreme low & lossing packets. (about 2~3Mbps bandwidth which means you download speed will be around 200K/S.) I did test my TPlink single powerline, and it can give me full speed (30Mbps) under the same network environment.
Summary: Like others, I got 2 PLS400 units instead of one PLE400 and one PLS400, so the picture is wrong. Also came is with 2 short ethernet cables. The "source" unit gets over 80 MB/S, but I only get 10 MB/S out of the other unit. Plug and play, thank god, because no instructions were included.
Summary: Like some others have experienced, I got 2 PLS400 units instead of one PLE400 and one PLS400. However, both units were bad as I have another set PLS/PLE units to work with. Additionally, the serial number / password stickers were removed.
