When choosing smart home electronics for a door, the hard part is deciding which version offers the right mix of finish, package details, condition, and price. These two Aqara U100 smart locks share headline emphasis on fingerprint access and Apple Home Key, so the useful head-to-head is Black versus Gray and what each package specifies.
Quick verdict
At USD 99.99, the Aqara Smart Lock U100 is the price-first choice for a shopper who wants Black and is comfortable with Open box condition. That combination gives the lower-priced model a clear role in the comparison.
At USD 124.99, the Aqara U100 Smart Lock Gray is the fit for a shopper who specifically wants Gray. The absolute listed-price spread is $25.00. Because the headline access focus is shared, the final call should turn on finish, condition, package details, and price rather than on the common U100 identity.
At-a-glance comparison
| Detail | Aqara Smart Lock U100 (Black) | Aqara U100 Smart Lock (Gray) |
|---|---|---|
| Listed price | USD 99.99 | USD 124.99 |
| Color | Black | Gray |
| Finish | Matte | Matte |
| Door handing | Universal/Reversible | Universal/Reversible |
| Package details | Hardware and Instructions | Hardware and Key; Fixings Supplied |
Matte finish and Universal/Reversible door handing are shared, so neither gives one model an edge. The useful differences are color, the black U100's Open box condition, package details, and the listed prices.
Where each model wins
Black finish and price
The Black U100 wins when the lower listed price is the first filter or Black is the preferred appearance. That gives Aqara Smart Lock U100 a straightforward role in a price-and-finish decision. Choose it when those priorities lead, without treating the shared Matte finish or Universal/Reversible handing as a special advantage.
Gray finish
The Gray U100 wins when Gray is the visual requirement rather than a secondary preference. The case for Aqara U100 Smart Lock (Gray) is therefore appearance-led: choose it when the lighter finish is the feature that makes the decision easy. If appearance is not decisive, the price comparison becomes the more direct tie-breaker.
Product notes
Aqara Smart Lock U100 (Black)
Black color gives the Aqara Smart Lock U100 a clear visual role. Hardware and Instructions are named in the package details, giving a concrete reason to choose the black U100. The limitation is its Open box condition, which matters to shoppers who put condition ahead of price or appearance. The black model is therefore best suited to a shopper who wants a darker look and a plainly described package. For a finish-led shopper, that is a concrete reason to favor the black U100. Choose Aqara Smart Lock U100 (Black) when those two priorities align with the project.
Aqara U100 Smart Lock (Gray)
For the gray U100, Gray is the immediate visual differentiator and the clearest reason to choose it. Hardware and Key are named in the package details, while Fixings Supplied adds another concrete inclusion point. Those details give the gray model a distinct purchase profile without making a shared attribute into an advantage. The limitation is equally concrete: Gray will not suit a shopper who specifically wants Black. The full product name also includes HomeKit and Keyless Deadbolt wording, but color remains the practical tie-breaker here. Choose Aqara U100 Smart Lock (Gray) when the finish and package details fit the project.
Final choice by use case
- Lower listed price: Choose Aqara Smart Lock U100 (Black).
- Black finish: Choose Aqara Smart Lock U100 (Black).
- Gray finish: Choose Aqara U100 Smart Lock (Gray).
- Universal/Reversible door handing: Both Aqara Smart Lock U100 (Black) and Aqara U100 Smart Lock (Gray) specify the same listed handing, so this is a tie.
The decision is straightforward: select the black U100 when price or Black leads, and select the gray U100 when Gray leads. The shared headline access focus does not need to break the tie.
