Reliable, solid build, great value.
As a professional handyman, I've installed a dozen or so of these for various customers. They install quickly, and the Smartkey re-keying capability is especially a big value add for customers with rental units. Strongly recommended, and I am a repeat customer.

Only locks I will buy
Only brand of lock I will buy. I have these on my personal residence, my rentals, and have installed them for friends and family. Kwikset Smart locks are easy to rekey, allowing me to make all doors and even padlocks work with a single key! How often do you lose the key to a padlock or have trouble finding it? Me? Never because it matches my deadbolt, my doorknob, my side door, etc etc. And if you lose the keys somehow, you can pull the cylinder and swap in new ones or get the tool to program them from scratch. No locksmith needed.

Kwik and EZ
Easy to fit in a existing cut and drilled door. Concise instructions and there's a key match function that I didn't need but if you have multiple Kwiksets yu can condense down to one key.
