I just bought a pair of Powerline CPL BeWan S200Maxx. Contrary to what I read on some tests (Digital), I observed after 8 days of fairly heavy use, no overheating of the housings. The performance given by the central LED (red / orange / green) are mostly green, indicating a very good transmission. The implementation is intuitive, and clear instructions for use. I am currently very satisfied with these products, and allows me to recommend it.
