Pros and cons

According to our door lock expert

Thanks to the included internet bridge, you can also open and close the lock when you're not at home.
The lock replaces the current cylinder, so it fits in almost every door.
Via the app, you can always look if your door is locked and you receive a notification when you forgot.
When replacing the cylinder, always check the correct dimensions, so the door lock fits in your door.
If you use the lock often, the battery empties quickly.

Top product!

Very easy to install (even with my two left hands)
Recently also with Matter
Can be linked to Homey and Apple Home

I was looking for a reliable and smart lock. After extensive research, I ultimately chose the Bold Elite. It's easy to install and integrate into my smart home (matter). It works with Apple Home and Homey, allowing me to trigger all sorts of smart actions when the door opens or closes.
