I bought one of these on the Anker deal (https://www.ozbargain.com.au/node/544749) and it arrived yesterday. My neighbour wants one now but Amazon is back to $349. I found the Amazon deal (https://www.ozbargain.com.au/node/547168) which is expired, and the JB Hifi deal for the $279 (https://www.ozbargain.com.au/node/547064) but they are 'Awaiting Stock' and delivery estimated in early August (plus there is $6.99 delivery charge). The good guys have this for $279 and it is in stock for delivery ($8.00) or free pickup. In the Brisbane area, 4 out of 5 stores I checked have stock.
Plenty of good reviews on this, some drawbacks, but overall the ability to avoid monthly subscriptions with Ring or Google and save direct to the included homebase is the key winner. Also, the Homebase acts as a chime and I believe with Ring you need to buy this separately.
Also 2.5% cashback.
