You can buy your eero mesh Wi-Fi system now.
eero has kept its promise made back in November that pre-orders of its mesh Wi-Fi system would ship by the end of February 2016. As one of the pre-orderers, I can confirm that FedEx will deliver the SmallNetBuilder three-pack by end of day tomorrow.
You can now also order eero from Amazon or direct from eero. Amazon is showing single eeros ($199) as "In stock but may require an extra 1-2 days to process" and three-packs ($499) as "In stock on February 25, 2016".
Other than that, today's blog post doesn't offer much new information. eero is still cloud based, is set up and administered using an iOS or Android app that begins the setup process via Bluetooth pairing, updates automatically and has "reimagined" guest access that lets you text guest network permission to users.
eero apparently already sent review samples to the usual suspects, so a simple search will let you know what they think.
