Great lock

Easy to install works well. The only problem I’ve found is that it opens the door too soon. As soon as Bluetooth connection is made, whilst I’m still getting out of my car. I need it to open when I’m a meter away not 10m. Same when I’m inside it would be great if it opened automatically as you walk towards it on the way out. Other than that it’s really good! Very strong and reliable. Batteries seem to last ages too 👍🏼👍🏼

Again, no idea what HappyCamper111 is going on about. Setting it up was a breeze. Bit unclear whether it had successfully paired with the bridge but you can check in the app or turn off Bluetooth on your device and try the lock via wi-fi. I have the bridge plugged in about 2 meters away from the Nuki. No issue. Love the fact that I can lock and unlock the door in so many ways, via Bluetooth or wi-fi, manually by turning the dial or by pressing the button and as long as you fit the right style of Euro lock, you can still use a key from the outside. This is a well designed device and app. Agree about the speed of operation - could be quicker but you’d have to be unreasonably impatient for it to be cause for complaint. Only reason I’m giving it 4 stars is because the build quality of the device itself doesn’t feel quite as robust as I would have liked - bit plasticky but it certainly does the job. Time will tell, I guess.

Excellent product, well made works every time

I’ve had a Nuki now for 6-12 months and I have to say I am as impressed now as when I purchased it. Very reliable, easy to use and fits UK locks.

The integration with HomeKit is a real bonus. Each night we have a scene that turns off lights, closes blinds, locks doors etc. But we also have a scene that unlocks the door if a fire alarm is triggered. Well worth the money.
