    • Works Great
Color: Silver
Great smart lock and installs easily. Connection and setup was easy, and fast. Having the hub is a no brainer as you can control the lock from anywhere you have an internet connection, and you can tell if the door is open or shut, locked or unlocked. Great way to permit emergency access when you are not around. ... show more

Originally bought a lock that didn’t come with the little WiFi plug in because we have several already and didn’t realize you couldn’t attach more than one lock to the WiFi device. So I returned that one and ordered this one. We have a back door that has a glass window with trim around it so we needed a super slim lock to go there. By the measurements on the description it should have fit with about 1/4-1/2” to spare… which it does AFTER it’s installed. Unfortunately I forgot that all of our other August locks attach to the mounting bracket with little wing clips that flare out from the sides about an inch. With them flared out you then align the lock over the mounting bracket and then close the wings back in to lock it in place. My measurement did NOT account for the little wings. We needed an automated lock for the door regardless and this was the slimmest one I could fine so I resolved to try and turn the mounting bracket as far sideways as possible to give more room for the wing clips. The clip still grazed the top of the trim but I was able to force it in place with only a small dent made on the trim when I was trying to force it. If it hadn’t worked I had decided I would just notch the trim. But I didn’t end up needing to do that. Once the wing clip was locked in I slightly rotated the whole lock to the upright position and everything works great. The device is only slightly lose because of how I had to have the mounting bracket loose enough to slide sideways. But it doesn’t wiggle on its own or anything. I’m super excited that i let worked out and I didn’t cause a crazy amount of damage to the trim or have to notch it completely. The reason I only gave 4 stars is I wish I had known/remembered about the wings. I wish they were shorter so I could have locked in place without any issues. ... show more

    • Best smart lock purchase!!
Color: Silver
This smart lock is AWESOME! Since installing I’ve never had to use my keys to lock or unlock my apartment door. Installation was super easy! Like seriously dumb proof! One thing to underline here is that the bridge does need to be placed like right next to the smart lock. What I did was just use a long extension cord and place the bridge right beside the door. Otherwise this product is dope! I have the settings to automatically lock the door after two minutes while I’m home. Then when I leave, the lock automatically locks when I drive away. Also for all you renters out there, this is 100% rental friendly! ... show more

    • Great replacement for Wyze lock.
Color: Silver
We have grown tired of Wyze so decided to try and replace it with the August lock. I'm glad we did. Works fantastic with Alexa and has the features I wanted. Auto lock, unlock, and Alexa integration.

    • Stay away, appears to be a scam!
Color: Silver
When I attempted to set up this lock I received a message that the serial number was already registered to another user and I need their permission to install it. Amazon makes no mention of the item being used or refurbished. It's sold a brand new. I called August's customer service. Same answer: we have to ask permission and wait for up to 30 days. This is a problem in and of itself: in 30 days it will be impossible to return. So, returning now. ... show more

    • Love it! Works great.
Color: Silver
I asked a product expert which August lock I should buy and although he tried to steer me to the one that had WiFi enabled, the worst he had to say about this one was that it was noisier and needed a separate connect unit. I don't mind the noise at all and the extra Connect unit is not a problem (I just had to create a separate 2.5Ghz band on my internet for it to work). I love that this uses normal batteries. As a photographer, I have tons of rechargeable batteries so I prefer using these (once the included batteries die) rather than a battery that has to be thrown away. I had bought the Level bolt before and couldn't get it to work on my old rental front door so I'm incredibly satisfied with how easy this retrofit installation was! Much easier, and less fuss. ... show more

    • great for dog sitters
Color: Silver
Loved having this on my door and was easy to set up and share with others! Had it on for almost a year and never ran out of battery. Shared it with dog sitters so they could come and go without an actual key being tossed around. Can’t stay signed in on the app with apple id though.
