I have the 3rd gen and these are my thoughts:
Pros:
1. Unlocks the door before you even get to it. For me, this is about 15 feet from the front door. I can't express how nice it is to not have to use my key. I have two kids, frequently carry groceries, takeout, bags, etc. I don't know of any other smart lock that unlocks on its own without requiring a pin, fingerprint, phone tap, fob, etc
2. Works with existing lock and doesn't show the smart lock on the outside. I have a highly rated lock that also makes it easy to reset the physical key. Not having to get rid of this lock is great. Assembly was very easy.
3. Works great with Google assistant. Part of my nighttime routine is having the door lock, has saved me quite a few trips to the first floor when someone forgets to lock the door. Also, I hate the way smart locks look so having the clean front door look is worth it.
4. Easy to setup and get started. Good guest access. Unlock and lock from anywhere via app
Cons:
1. Android can be more finicky with auto unlock, I've had to reset things on my phone a few times. Wife has an iPhone and never has had issues.
2. Auto-lock features not nearly as robust. I don't even use it, more likely will lock myself out if I do
3. Takes a lot of batteries. Battery life is good, maybe changing the batteries every 7 months or so. You get lots of notification when batteries are low. Lock is still fully functional with the physical key of battery does completely drain
4. App can be slow or unresponsive at times
1) Goes through batteries. I have to replace every 3 months
2) If you use Apple Homekit the syncing can be a bit sketchy.

1) Decent & handy for iPhone users
2) Bad for everyone else
3) Uses Bluetooth for proximity detection to unlock (worrisome - BT tends to have lots of security holes that never get patched, but only fixed on NEWER hardware because they exist in firmware or on silicon). BT is great for audio, maybe lights, etc. Never trust it for security.
4) Uses WiFi to connect to your smart home hub and/or the internet. Insecure, and dangerous to allow a wifi- connected device to unlock your door.
5) Doesn't have Zwave (a standard, pretty secure, reliable wireless standard for IOT stuff) or Thread (very secure and part of the Matter standard). Zwave has been recommended for locks by security & smart home companies for years. Either of these would make it MUCH more secure, AND extend the battery life- a lot. I go 8-12 months on 4 AA's on my Zwave locks. Wifi sucks a lot of power and is terrible for low-bandwidth devices that don't plug in.
6) If you aren't carrying keys and/or you left your phone inside/ phone battery died/ kid without a phone, that person cannot get in because of no keypad.
There are lots of great smart locks out there with some cool new models coming on the scene that support Matter and Thread, making sure they're extremely secure, never rely on the internet (like Homekit), and can always be controlled by whatever your favorite smart home platform is (Alexa, Apple, Smartthings, Google Home, etc.) or will be in the future without having to worry about support ending. You can even control from multiple things at the same time.
Speaking from personal experience, the keypad models (with Zwave or Thread) are great, and I can easily set and unset up to 10 different codes through a phone with Smartthings to make it painless for kids to get inside without worrying about carrying backup house keys that get lost or stolen. If I have a houseguest or a neighbor needs to come over to check on the dog, I can just set a temporary code for the keypad and they don't need to install an app. Some people really don't like keypads though, I guess.
Edit: Also, August has had bad issues in the past with their locks being able to be used to hack into your Wifi network due to poor security practices on their part. That could happen to anyone but the point is its a bad idea to mix Wifi and door locks. You're at the mercy of the security implementation of a complex little door lock's software as well as whatever poor security may exist on your Wifi network.

AFAIK most smart locks over the years have been Zwave or Zigbee, which have been around a long time, although I could be wrong. Zwave and Zigbee (similar'ish to Zwave) don't have IP addresses and work over a lower-level wireless protocol, so your average punk walking around with a wifi scanner/hacking app or tool isn't going to be able to do anything with it or even see it. Wifi Ethernet+IP is complex, hard to secure, has constant holes and security weaknesses, and is extremely widespread so it's an inviting target vs. a much more obscure low-level home wireless protocol.
Now Thread, which is based off the radio part of Zigbee, *DOES* also have IP on top, but it's IPv6 with a lot of fantastic encryption and security built in on a separate little IPv6 network that is NOT connected to the internet or your home network, but only connects through a thread border router (usually your central smart home hubs like Smartthings, an Alexa or Google or Homekit or Vera or Home Assistant or ... device) to which your phone or computer or other device or cloud service talks to. You have a very controlled, minimized attack surface - one little gate that is kept very secure.
Now constrast that with Wifi where each device can individually talk to not just the Internet, but any other device that can get onto your Wifi or wired ethernet network. It is very difficult to keep servers and workstations at big companies secure, and they get a lot of attention. Small little devices running Wifi have a LOT fewer people trying to secure them and constantly check for vulnerabilities, and sometimes massive ugly security holes are found many years after they've been in the wild (like that horrible new Eufy camera problem that was sending facial recognition data and user's authentication info up to the cloud, sending security info (like passwords) in cleartext, making it possible for anyone to watch people's live camera feeds without logging in, etc. All for cameras that were designed for local use.) Plus when holes are found in Wifi IoT stuff, fixes may take a very long time or they may not be updated at all because newer products are available.
Also don't forget the part about Wifi radios and the processors needed to run them sucking a lot more power. That matters little on your laptop, a little more on your phone, but it's a big deal for something running on batteries when Zwave, Zigbee, and especially Thread is super power-efficient. It's also a waste. Cameras, laptops, TVs, etc., need Wifi bandwidth but doorlocks sure don't and all that risk and wasted power brings no benefit.

If I am to buy another, I would purchase another 3rd generation. Have had no issues to date. Still going strong.
Granted the bridge does drop out once in awhile but it always finds a way to reconnect. Has not been a problem for me.
Based on all the posts here & everything else I've read about the 4th gen, I think getting the 3rd gen would be better, since the only negative seems to be that it's bigger/bulkier than the 4th gen.
i had just bought the 4th gen about a month ago. I haven't gone through a battery yet. So if I have to keep 4th gen anyways should i get a bridge?
Would bridge help with battery life?
