The hardware feels nice along with the included fasteners and adhesives, but I wish the plastic cover for the battery, programming reset button, and Wi-Fi module compartment felt more substantial. That plastic part does feel like something which could break easily (I could see someone dropping it from popping it off to replace the batteries). I like that it's plastic for Wi-Fi reception, however. Obviously, that's better than if it were metal or some other material that would interfere with signal. I'm comparing this with a Z-Wave Keypad Combination Keyed Deadbolt I am replacing from 2017 from another common lock manufacturer who will go unnamed - it had a much more substantial feeling cover and was a less expensive lock (also a plastic cover). Too bad Z-Wave is so unreliable with anything that I had access to with HomeAssistant...One other concern is that it will intermittently not be connected to Wi-Fi during hotter parts of the day. It still works with Bluetooth during those times, but it's concerning for the long term of the product's life.The setup is a little interesting / cumbersome with the app and the booklet, but once it's installed it's so much nicer than z-wave and using a keypad or a key! For instance, with the application, you have to tap to get rid of some video interaction buttons that don't auto hide when you start a video for a new step of the lock installation. Prepare to tap on the screen so you can see the step, each time.I unfortunately ripped some paint off while repositioning the magnetic sensor on my door. So be forewarned that the 3M foam dual sided tape is not kidding around!Another gotcha - be very certain that if you need to unplug this thing (outer keypad from the inner module), use some sort of plastic spudger / nylon probe tool so you don't strain the delicate wires and plastic connector with your fingers when disconnecting the Molex like plastic connector... I had a very difficult time trying to find my electronics repair kit with the aforementioned tool to undo the cable so I could take off the spacer which is preinstalled on the keypad module (since I had mis measured). I didn't have to re cut my door whatsoever to get this to fit. I was a little sad that the Yale handles weren't in stock, but I found a matching handle at local hardware store that ended up fitting.I have a few 9v batteries stashed in some secret accessible locations in case the batteries die at an unideal time, but I hadn't ever run into that problem on my old lock (which failed mechanically).Another thing, I would have preferred a darker brown color, but oh well. I need to paint the door a different color anyways to get rid of the ugly lines left by the indentations of the prior deadbolt and handle.I like the packaging that it comes in when ordering from Amazon - it's recyclable carboard with minimal ink / dye. You get everything you need in the box aside from say a screwdriver and or a drill / borer for the magnetic sensor if you plan on mounting it flush within your wooden door frame.Using the lock feels flawless with Homepass. Just bring your Homepass card near the door and it opens. It's also cool to setup automations to just unlock or lock the door when you've arrived home (say from you triggering your Garage door with Homekit or something like that) or when you've left (same thing). Bluetooth + Wi-Fi is the way to go with this for reliability and the keypad for the backup.For those worried someone could just yell at your Siri or what not (say to your Homepod or Homepod mini) to open the door really loud, you actually can't do that even if you wanted to because it'll ask you to continue on your iPhone where you've installed the Yale App to authenticate that command. I think Yale and Apple really covered all the bases with this product. It's got a few things to be desired, but in my opinion it's the best smart lock product for your iOS family and Homekit and Homepass on the market, as of right now.Forgive the ugly paint!
