I figure I should update with my findings.
I mainly use local access (with Bluetooth) between my wife and I. We both use fully updated iPhone 6's, and have the Lockitron app installed on both. To cap it off, I haven't carried my house key on me for a while. I took it off my keychain after getting the Lockitron, and finally put it away around the start of April. I've been able to enter/exit without issue so far. We don't have any guests with access - there's been no need for anyone to come over while we're away/out. I can easily reach the lock via Bluetooth from just about anywhere in the house, so I just unlock the door when someone is coming.
On Battery Life
As far as batteries go, I do find it lasting a very long time, much longer than the crowdfunded unit. I've easily been getting several months out of any particular set of batteries. I haven't measured it exactly, but suffice to say it's pretty much living up to the claims. I have confidently invested in a set of Eneloops, and I've dedicated a set of four to the lock. I actually can't remember the last time I charged them, so they've been running for a long time (which is a good thing).
Stay tuned... HomeBridge is working for a few other things though, and works well. Looking forward to automation with this, and having a presence detection system enable auto-locking after entry/exit. The Lock Reminder in app is handy too.
On Build Quality
The lock is very well built, looks and feels solid. My wife likes the Quicksilver, and it matches nicely with our white door interior. On the outside, the lock looks right at home with our polished nickel handle. Turning the deadbolt by hand has a nice click to it, so locking the door feels "strong", and it inspires confidence. My wife and I do appreciate being able to see the "lock status" by looking at the thumb turn from down the hall - It's clear what state it's in, and we don't have to open the app to tell.
99.9999%. Yes, we use iOS, and this has been known to work better for Sense (both past and present), but it has been very solid for us so far. Any hiccups have been few and far between, and upon further analysis, they were caused by other factors. When it comes right down to the app, my phone, and the lock communicating together, it's 100%.
I can get a notification that my wife has locked the door after leaving, and this is a good thing. The notifications have been a little in and out, but they do fire. When they don't work, I think it's down to two reasons. One is that external factor I just recently mentioned, and the other is probably the app being closed from memory in iOS.
The logging has been pretty consistent so far. I can't speak to Guest logging, as we haven't invited any. There's some ordering issues when events are very close to each other, but it's very small. It seems to be just when items are reported close to each other. Regardless, it's easy to tell the status with the main display for the lock. We're mostly using the lock by app, so our activity is getting logged. The few times we have manually locked/unlocked, it's not logged, but the status is correct in app. I believe this is getting worked on.
The App (on iOS)
Loads much quicker than before, and I like the new button style. The design of the app feels a lot better now - it has matured well. It's quick and easy to get in and out of the areas you want. The widget for the Notification Center is a nice touch, eliminates the need to actually open the app for quick unlock/locks, but I still go to the app out of habit. Battery usage is minimal, largely due to the structuring of CoreLocation services on iOS. It's to the point where it doesn't even register as 1% battery usage in my iPhone settings, which is very good.
Went pretty smoothly. Took me around 30 minutes, but that's because my door is a little "weird" - the deadbolt had to be pulled out a little more, and the previous latch plate was screwed in wrong. I was able to resolve those issues on my own. For the material, the instructions are clear, and the video is a big help.
Overall, I'm very satisfied with Bolt, and it has won over my wife. She's found Sense to be immensely valuable when coming home - she doesn't have to dig around in her purse for her house key. As for me, it's been enough to leave my key at home, probably for good. All I carry in my pockets are a slim wallet (three cards), car key, and iPhone.
There are some small things here are there, but they don't detract from the overall experience, which has been largely positive. Some fine tuning and those little edges can be resolved. As I mentioned, everything physically works well, and the software runs well along with it.
I give the Bolt in it's current state a 95/100, based on our usage.
