I bought PLC due to price display and relative to the brand.
I would say it Netgear Powerline XAVB5421-100FRS do the work; we must not forget that to have CPL 29.90.
For me, the CPL are best for quality / price, even if it is true that the DEVOLO brand are the best but the price is high.
To conclude:
The CPL appropriate for all customers who seek a stable connection to surf, watch videos or play video console 29.90, what more?
