Regular price is $74.97, but on sale for $54.95 plus 10% off if you buy 4 or more. Best deal online is at Costco where you must buy a 2-pack for $119.99 [costco.com]
The Kidde is a bit more expensive, is hardwired and takes AA batteries for backup. The one you need for new construction, where hardwired is a code requirement. It's Wi-Fi, so no Ring hub required.
The First Alert is ~10% cheaper than the Kidde, is 10-year battery powered. Not hardwired, so only suitable for adding to existing systems or replacing hardwired units, no-go for new construction (at least until the inspector leaves). It's Z-Wave, so Ring hub is required.
3rd option is any old brand of smoke detectors plus a Ring listener, a lot of people like this option, but with interconnected units (as is required by code where I live), it'll be tough to figure out which one went off first. Not sure how to solve that one...
What I REALLY want is hardwired + not $$$ + Ring compatible + Zigbee/Matter/Thread + 10-year backup battery, but such a device doesn't exist apparently...
