Now my purchase of two August products worth hundreds of pounds is not even half as useful as I thought they would be
Amazon or the August product descriptions never pointed out the fact that the August skill is not available for Alexa outside of US. Now my purchase of two August products worth hundreds of pounds is not even half as useful as I thought they would be. Stay away from this if you are not in US.

Dissapointed
I tried the second and 3rd generation locks, fitted by a locksmith and neither of them worked, they would not turn the lock far enough, very disappointing

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!

Remote access but difficult to install if not deadbolt initially

I finally upgraded from the original first gen round August Lock (which I've been happy with your several years now) to this third gen version. The biggest reason I wanted to upgrade was the fact that the design of this one is like a regular lock. While the round one was working just fine, unfortunately other people unfamiliar with the lock just became baffled on how to unlock the door from the inside. With the design of this one, that eliminates that confusion for guests and it looks like a normal door lock to them. The additional features I like compared to the first gen one was the addition of the door sense feature. I haven't experienced it enough yet to really comment on it, but the initial testing of it was nice to prevent it from trying to lock when the door was still open. The issue I did have on the first gen one was that it could sometimes jam the lock if it tried to lock when not fully latched or closed. This one so far also seems to be a lot better with the smart alert notifications. The first gen one was hit or miss when notifications would actually work with the wifi hub. But so far this new one seems to actually notify every time per my settings. The only negative thing I have about the third gen vs the first gen is the missing sounds. On the first gen one, you could have it make lock and unlock sounds when used by the app or auto lock/unlock. Unfortunately the 3rd gen doesn't have the sounds built in. It is louder when the device is working, which somewhat substitutes for that so you can hear it working, but I'd still rather have the lock and unlock sounds option. Outside of that flaw, it is still a great product. If you are a renter, it is also perfect as the original keyed entry doesn't change, and you still only swap the inside part, and when you move out, you simply put the original inside piece back. That's why I preferred August Lock from anything else. It is simple, yet effective. Now I have a spare first gen one, maybe I'll just use it for the back door.

This is a fantastic lock especially if you live in an apartment with strict strata laws. The lock looks normal on the outside because the smart lock is installed on the inside. Because of this, you can still use your regular keys to open the door, especially when/if the lock runs out of battery. Everything is installed and optimized through your smartphone and is unlocked/locked via Bluetooth connection. It comes with door sensors so it can automatically sense when your door is locked, meaning that you can walk away from your door without any worries. At most, it will take you roughly 15-20 minutes to install. Within the app, you can invite family and friends to have either guest or owner privileges to your lock which eliminates the need to cut keys for them. You can also track who opened your door and how (manually or wirelessly) and at what time. This lock gives you so much control for your home and it's the best investment that I've made in the past 5 years. They do need to make some improvements to the application itself since it can be quite slow in connectivity, but you can't really expect much from Bluetooth connections. Highly, highly recommended!
