Re: D-link products are a bit shit. News at 11.
"Normally the only time you buy D-link is when it's a very lightly re-branded piece of kit that's known to be decent, and that if it features firmware, can be updated directly from the manufacturer."
Actually, I could buy only D-Link products that are dumb and non-configurable: PoE injectors, transceivers, antennas etc. Even L2 switches when latency, buffers etc are of no importance.
Of course, I could just as well procure even cheaper brands for those operations. TP-Link comes to mind...
