Pros: Fast, little difference in speed as compared to plugging your ethernet directly to the cable modem / router! Works just as well on outlets connected to different circuits! I bought 2 sets, so I have one connected to the router and the other three give me ethernet connections in different rooms.
Cons: There is no pass thru outlet, so you loose an outlet when use it.
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.
It extended my network but it disrupted my existing wireless network

Summary: I can't use this now and since it is defective I need to pay to have it shipped back....
Pros: When it was connected on the same circuit the speed and latency was great. Easy to setup. I was able to stream 1080p at 60fps to my tablet using Limelight for gaming downstairs.
Cons: When it was plugged in with the same room as my wireless access point it would start dropping signal. I tried two different access points since I thought maybe there was some bad shielding in my PoE AP but both had issues. It wasn't until these things were removed and all my equipment was rebooted did my network come back and I could stream movies again.
Summary: I live in a a two story with router upstairs and use this to get a better connection to all of my home theater devices on the first floor. Although I purchased the single port I have it wired into a switch which works great. I am now able to get HD stream, which I was unable to get over wireless. I purchased this for under $20 which was a fantastic sale price.
Pros: Works out of the box Awesome sale price Excellent connection
Summary: Bought this in order to move a WiFi Access Point to a more suitable location. (Could not run new wiring.) The setup could not have been easier & it works exactly the way I need it to. Now the WiFi AP is in the family area while the rest of the network gear is out of sight.
Summary: How can this be advertised as having 200Mbps speeds when the LAN connection is 100Mbps???? In any case, when connecting these next to each other on the same circuit (ideal scanario) I only got half the transfer rate of a direct connection. The 1GB folder was transferring at a rate of 12Mbps vs >6Mbps using the PLEK400 (as measured by Win7). In my target location I got much worse speeds which were even lower than wireless.
Pros: Not sure there are any unless wireless is absolutely not an option...
Cons: Slow, even side by side... REALLY slow when on a different circuit (same panel)
Summary: I have Cox 100Mbps internet. I average 87Mbps on a wired computer. Connected PLEK400s to router and to this same computer. Now I only get 56Mbps (at best). The PLEK400s were on the same power wire (two outlets in the same room, same circuit). Next, moved one PLEK400 to a computer in another room (different electrical wire, different circuit). Now I'm lucky to get 20Mbps. That's a huge drop! I tried upgrading the firmware, but that didn't help.
Pros: Easy setup.
Cons: Speed results vary greatly from outlet to outlet. Linksys Powerline Utility crashes on Windows 8 (works on Windows 7).
Summary: Usually don't write reviews, but I'm really happy with this product. We had SO many devices using wireless that the frequency was saturated. Laptops, phones, two desktop computers, AND our wireless cable box. Every time my kid would download, the TV would digitally pixelate and freeze. I was skeptical this product would work for us because our home wiring is old old, much of it only 2-wire with no ground. We literally plugged these units in, hooked them up, and it works.
Summary: This serves as an inter-connect between the wireless 4-port switch/AP in the living room (back of the house), with the router and upstairs AP (the front of the house). Wireless gateways didn't give me the throughput I needed for streaming. This solution tested out at 25 Mbps to the Internet (my max allowable download speed). House wiring is less than 10 years old.
Pros: - easy to setup - works as advertised - ordered it and had it on the front step in less than 24 hours (and that included free, 4-7 day shipping)
Cons: - buzzing from speakers plugged into the same circuit; this is not a bother and I should be able to isolate it - watching closely for disconnects while streaming but so far haven't encountered any hiccups - takes up considerable space on the outlet making other devices hard to fit (must be straightline). My solution was to use pigtails and plug the PLEK500 transceiver into the pig-tail.
