These are normally expensive (~$210-$230), and still more expensive than the TP-link powerline adapters. But I prefer this model because it has Wifi Mesh and 3 Ethernet outlets apart from a powerline passthrough option.
This is the cheapest I've seen it in a long time after Centrecom had them for $149. Still a good deal if you add the ASUS promotion from here: https://www.ozbargain.com.au/node/463725, and add the CashRewards cashback on top as well. Shipment from Umart varies a lot, so that might be a deal breaker for some. Price match with stores is another option.
So does this mesh with your existing wifi network when connected?
