We use it for our guest room and it solved the old key mess; access is quick, setup was a little fiddly but worth it, and the backup key calms my paranoid side about batteries dying at odd times.

At first I was skeptical about fingerprints, but after installing on a bedroom door it's been reliable every day. Rechargeable battery is convenient, and having a manual key gives added comfort when tech acts up.
