After a year of using the Schlage lever lock, I'm very happy with the quality, reliability, and usability. I have a high opinion of Schlage, and this lock has not disappointed me. It works great with Vera, and I'm very much a convert of the keyless door, especially when you combine it with the ability to control it the lock remotely, schedule its locking and unlocking as desired, and receive instant notifications when people enter their PIN codes.
I've also been testing both the Kwikset locks, deadbolt and lever, for a few weeks now. I must say that I have been surprised by both these locks. They have a much higher build quality than I was expecting. In fact, the lever is so solid and smooth that it feels like it's a commercial/industrial grade unit. These locks have both been operating flawlessly for me with Vera. The SmartKey feature made it super simple for me to change the keying to match my other door locks.
So, in my opinion you can't go wrong whichever lock you choose to install in your Vera system.
