Great, low-cost smart lock!
If you live alone and only have one door, this smart lock is all you need. It locks the door behind you when you leave, it unlocks the door for you when you arrive back home, and finally, it locks the door again a couple of minutes after you enter. What else do you need? I really don’t see the point in spending the extra $70 for the wi-fi adapter. I got this one on sale for under a hundred bucks on Amazon and especially compared to all the alternatives in the two to three hundred dollar range, it is a real bargain! Installation is a breeze. Total time to physically install the lock is 5 minutes. It takes longer to get the Android app configured. I did not install the “door sense” feature as I am not sure it is needed. Again, I live alone and am pretty good at closing the door behind me. I may change my mind at a later time and will update this review if I do. Unlike some other reviewers, I have not had a problem with the Bluetooth connectivity. Using the android app to manually open and close the lock, I find the Bluetooth range to be at least 30 feet from the lock both from inside and outside of my front door. I can even unlock the front door with the app from my bedroom which is upstairs and on the opposite side of the house. I also don’t find it necessary to have wi-fi turned on on my phone as the instructions recommend (I have an unlimited data plan so I usually leave wi-fi turned off to save battery life). Still, the lock seems to know I’m home as I am parking in my garage as I get a notification on my phone. Some reviewers have complained about the Bluetooth being slow and lagging, but I haven’t noticed that. Maybe it’s because I have a detached garaged and it takes me a while to get to my front door. My existing door hardware is a dark bronze color, and the dark gray August Smart Lock 3rd Gen is a pretty good match so it looks smart and yet unobtrusive on my door. The fact that low-tech people can still use a key to enter and manually lock or unlock the door on the inside is a big plus. Overall, two thumbs up and five stars for the August Smart Lock 3rd Gen!

Great lock but....
I have had several August locks over the years and they are amazing! They work great and are mostly very reliable. ...but....I recently had 2 issues: The first was with the keypad which would not respect the settings. Annoying but not critical. Then a lock that was less than 3 years old up and stopped working, it acts like it's closing because the internal gears are broken. August's support was helpful and nice but in the end, they say that's too bad here is a 20% off code to buy another one. But their Amazon store is already priced ~30% off so that does nothing for me. But bigger the issue I have with this is that August does not care to even get the device back to test why it failed and to fix the problem in the future. Better yet, if they are able to fix the problem and resell it as refurbished. But no, I have yet another paperweight of worthless tech in a paperless world.

Motorized and app driven works well. Automated unlocking could use some fine tuning.
I bought this lock as a stand-alone item (not tied into my network with the optional network interface). It works as expected and I would purchase it again. Notes: 1) Physical installation: Simple and straightforward - takes about 20 min. If you can operate a screw driver and follow directions, you can do this installation. Start by installing the app on your smart phone and fire the app up. That will walk you through the process of doing the physical installation of the hardware. 2) Minor installation issue: One of the side wings that keeps the lock unit on the door keeps drifting open. I keep pushing it back in - the unit has never actually fallen down / off, but this is slightly annoying. 3) Installation note: As advertised, this product does not interfere with the use or appearance of the outside lock or your existing key. 4) Unlocking: I have it set up to unlock the door when I get back within range of the house. Around 2/3 of the time as I'm walking up to the door from my car my phone will vibrate and I hear the door lock unlock. The other 1/3 of the time I either have to wait a few minutes or pull out the phone, open the app and unlock the lock. (I have an iPhone 6. However, cell service stops working about 4 blocks from my house and "comes back" via WiFi connection when I arrive home.) Once the app realizes that I'm back home, it always opens the door. 5) Locking: I found the automatic locking via a timer to not work for me because I go through this door a lot when I'm home. You have to be a good solid block away before "away" mode is triggered. I expected this behavior and I have just been using my house key to lock the door when I leave. I haven't tried telling Siri to lock or unlock my door. I would give this product 5 stars if it would always unlock the door when I come home and if the attachment wings would stay put. I still rate this product as a 90-95%, not the 80% that a 4 star rating implies.

Works as described. This is my 2nd August. The old 1st gen pro broke down after years of abuse. Love the auto-unlock function. It’s the best I’ve experienced and it works very nicely. Would have gone for the pro but couldn’t find one on offer without the connect.

La instalación es muy sencilla , es un excelente producto , el manejo por la aplicación es bueno y mejora con el dispositivo August Connect. Es bueno verificar que tu cerradura si sea compatible, en mi caso quedo excelente!

When it says works with google home and Alexa its a bit of a cheat, that works only if you purchase a second bit of hardware. So i give 1 star less for deceiving marketing. Very easy to install and setup though my daughter had problems with a sub sim of the main sim. Ie a sim card under a contract of a master sim. When that was swapped out no problems. The open when you approach is a bit temperamental. But does what it says on the box and good value. If I had to be really picky the opening and closing motor twirling noise makes it sound a bit cheap and nasty. Maybe thats why Samsung locks plays a tone during opening and closing to hide the noise?

August refused to support this product in Australia if there are any issues you are on your own my product now is intermittently dropping Wi-Fi signal and the response is if I disconnect from my Wi-Fi to reset the device I will not be allowed to set it up again because it’s not supported in the Australian region
