Community Reviews

The Aqara U400 is a smart lock aimed at Apple households and Matter over Thread setups, with fast hands free unlocking, keypad access, backup keys, and broad support for HomeKit, Google Home, Alexa, and Home Assistant. The Costco bundle stands out for including the M100 hub and two batteries, and the hub alone is valued at about $30. The lock is also praised for reliable auto lock and easy installation without changing existing locks. The main hesitation is price, since similar bundles are close to Amazon and some prefer cheaper AA battery models or older Schlage locks.

Is this the same body as the DELUXE model that Apple sells?

This isn't the deluxe version that Apple sells, is it? It doesn't appear that it is to me, but if I'm wrong and it is, this is an easy buy.
Trying to figure that out also. Did you find out if it is the same DELUXE, that Apple sells?

Idk why people are saying this product is inferior. I have the Apple deluxe one which basically has more metal and an extra battery. As an iPhone household it's like magic. On a super rare occasion I might get to the door and it takes a full second to realize I'm there and unlocks. 99.9% of the time the door is unlocked as I approach and locks once I shut it. Charge lasts a long time too. It's been about 4.5 months and I'm down to 60%. Love that it has a key in case of failure but I've never had to use it once since I installed it. Highly recommend if you're an Apple family.
Do you know if this Costco package version is the same as the Deluxe version you got from Apple?

I just ordered the Costco deal.

I was originally planning to replace my Eufy smart lock with the Aqara U100, but once I saw the U400 with UWB support, I decided to go that route instead. I first ordered the U400 from Amazon for $269, but it's still unopened and I'll be returning it once the Costco order arrives.

The Costco bundle was just too good to pass up since it includes two batteries and the M100 hub. I already have an M3 hub that I picked up from Facebook Marketplace, so the M100 is really just a bonus for me.

I've also seen some confusion about whether this version is the same as the one Apple sells. My understanding is that the Apple Store version is more of a premium-finish variant, with more metal and a more upscale exterior design, while the internal lock mechanism and core functionality are essentially the same.

Someone please correct me if I'm wrong, but I believe the main difference is that the Apple version looks and feels more premium, while the Amazon/Costco version uses a bit more plastic in the exterior construction.

Yes. More metal than plastic on the Apple version. But same insides
