The metered 15A PDU works fine. I use them for two home vSphere lab setups with 3x 1U servers and a NAS plus a couple switches and a firewall. The two front ports are handy when for whatever reason I need to plug in a laptop or a small switch or the like while temporarily in front of the rack. The accuracy of the load meter is good enough to have an idea what is going on.
Be aware that the reviews here apply to all of the different models being sold on this page, so for example the top review complains about problems during firmware updates, but most of these models don't even have remote accessibility or firmware to update.
