We had a first generation August lock that died and since we already had other August products, I decided to remain in their eco system even though I did not think much of the 1st gen lock - so much so, I started looking at other brands.  I am SO glad I stuck with them.  This product works like you want it to!  Bluetooth sensing when you leave/arrive works timely, the speed of the manual interface on the app is significantly improved, the form factor is smaller, and the battery cover doesn't just fall off because you don't have the "special" touch like the gen 1 required.  I only wish I had upgraded sooner!
