I've had the Gen 1 lockset installed for several months as well as the internet gateway.  I have been VERY pleased with this lockset and the ease of use for end users and for me as the admin of the electronic keys and internet gateway.  Locking with the iPhones has been easy since Day 1; same thing once we got the $99 internet gateway.  I would rate it 5 stars, but I still have times were the lockset will lock itself and often when I don't have any phones or fobs nearby.  This leaves me stranded outside until someone lets me in or I find another means into my house.  Locking without the presence of a phone/fob and without touching the bezel is a HUGE problem, thankfully it doesn't happen every time I leave my house.
