Summary: I purchased this and was happy that it worked right out of the box. A way better option as the wifi signal from one corner of the house the the far corner in the basement was weak. I've plugged a hub in to mine so that my PS3/WiiU/etc all have a fast wired connection. I haven't needed to use the sync buttons or the utilities on the disc, so I can't comment on the problems the other users have had.
Pros: Very easy to set up, Reliable fast connection, No wires across the house
Summary: Bought 2 units (4 adapters in total) to extend/stabilize wireless coverage. These work great until any of them disconnects... Then it's a nightmare trying to reconnect it because the hardware buttons (sync and reset) don't seem to do anything!
Pros: Frees up its outlet, More consistent than wifi
Summary: There is essentially no documentation on this device. The CD that comes with it (containing some utility software, also undocumented) contains a PDF of the included picture. If they wanted to save paper I'd understand, but it seems like they were just too cheap to get proper instructions done. The picture instructions only show how you should and should not set it up with a power bar.
Pros: Simple setup, works out of the box
Cons: Severely lacking any documentation. Just comes with one picture of instructions. That's it.
Summary: This powerline package was definitely what I expected. It is more reliable than wireless and less messy than a direct cable in the house. All and all I would not mind buying this product again.
Pros: When its on sale it is a great deal. Also no need for wires around the house anymore
Cons: Other than the tricky cd and the fact that this isn't free, what bad things can I say about this product.
Summary: I plugged them in and they worked no problem. To add some security I tried to use the sync buttons they stopped working all together. I tried all the suggested fixes as per the manual nothing worked. The buttons on the devices themselves cannot be relied on, you MUST have a Windows PC kicking around. I use Linux so that was an issue for me. You need the Utility software to get into the devices and change the network names and get them working again.
Pros: It does what it is supposed to do. If you don't have WIFI then this is great.
Cons: A good WIFI connection is faster., Must have a Windows PC around to fix the units after you try and use the sync buttons.
