Summary: -Like some others have reported, there is a faint high pitched noise. I have to turn my head a certain direction just to hear it. Although you won’t hear it if anything nearby is making noise also. But this could be a big negative to some people, depending on how sensitive you are to it.
Pros: -Nice compact size
Cons: -Not anywhere near the rated speeds, but that is typical of all the Powerline brands sold.
Summary: Other minor drawbacks are the LEDs on the front of the unit. They are not of a uniform intensity, and the light from one indicator bleeds into the next. So it can be difficult to tell whether the ethernet or the PL light is blinking.
Pros: Overall this is a neat little device. The biggest perk is that this kit comes with everything you need to get internet from near one outlet to another. Simply is a plug and play.
Cons: My biggest complaint about this product, is that one of the units has a high-pitch whine to it. It whines any time it is plugged in (with the exception of when it is in sleep mode). This is the reason I gave 4/5 eggs.
Summary: If your outlets are far apart (see transfer rates above), things get pretty slow. It isn't the physical distance between outlets, it's the "copper distance." For example, it is possible for one power receptacle's outlets to be wired on different circuits, potentially with 50+ feet of copper distance.
Pros: I am happy that power line networking has matured. My experience so far is that it is more reliable than wireless and doesn't involve drilling holes like standard cabling.
Cons: Unfortunately, long distances are not a strength of the Trendnet 200AV.
