Pros: I currently have 3 of these adapters (with 2 more on the way), and they are perfect for my needs. Since my house does not have ethernet connections throughout (and I have neither the time nor resources to set up that kind of system), I have resorted to using these adapters to: 1) Set up wireless AP's for blanket coverage throughout the home. 2) Have clients hardwired to the powerline adapter through the access point. These adapters are much more reliable than wifi, and they allow me to set up AP's in areas where it would be optimal for coverage. They do run quite warm, though my oldest two adapters seem to have no ill-effect from constant usage (for over a year).

Cons: These adapters are very distance-dependent, and can vary highly in performance depending on the type of plug and location. While these adapters are stable (and more reliable than wifi), their connection over the powerline adds a degree of latency that may or may not be of concern. In addition, as these adapters are reccomended to be plugged directly into a plug (as opposed to a power strip), you do lose access/flexibility.

Overall Review: Don't be worried about the refurbished nature of this product. My package was in a nondescript brown box (as opposed to the typical retail box), but the adapter was spotless/perfect condition.
