Easy functional.
Easy to install. I needed to replace a booth lock and this item is easy. It sticks when I close it so be mindful when locking from outside that you hear the confirmation that the door did in fact lock. I like that it’s either code or key. Easy to open with code when I don’t want to fumble for keys. Battery life has lasted since I purchased.

Painless, good
Easy to install, exactly what you’d expect / hope for. Installed maybe 2 months ago and it’s very quiet, it just works as advertised and is sturdy.

Great Functionally, Good Quality, Excellent Value
I’ve tried two other brands but this product proves far better in functionality and quality:* keypad has proper firmness & feedback response (not mushy keypad feel like other brand)* lock & unlock mechanisms instant reaction (unlike others which makes a lot of noise before mechanisms engaged)* key lock is flush giving cleaner modern appearance (I guess this could be personal preference, it’s cleaner look to me)* The casing material is good* Excellent price value

Very easy to install
Why did you pick this product vs others?:OMG I have been saying unwanted one of these since I purchased my home 3 years ago. I was so afraid thinking it would be too difficult to install. When I say this was easy as 123. Literally installed it myself in about 30 min max.Guys if you are looking for a simple keyless system buy this!!!!

Water from front door easily damaged the lock and it stopped working.

Works perfect
Better than others at half the price. Even let me know the batteries needed replacing while I was setting it up. Had returned a higher price model because I didn’t know the batteries were low and that was why the other expensive brand didn’t work.Easy to install and clear instructions. Voice prompts for auto lock is nice. Let’s me know door was shut all the way and lock engaged as I’m walking away.
