I had been using the U100 since it came out and been quite happy with it all this time. The use of the new tech, NFC, made the decision for me to make the upgrade. I moved my old lock to the back door and installed the U400 on the front. I am amazed how fast it works on approach. My phone or Apple Watch, it is fast and reliable. One other major reason for the upgrade, it’s rechargeable - a big selling point in my book. It took a minute to get it connected correctly in the Aqara and HomeKit apps, but once that was done, worked like a charm. I Love it!

I’m super jelly - I’m from Europe and we don’t have it here. But hearing so many positive comments about U400 I’m very impressed. So glad you’re enjoying it!
