1. So far, no issues with fingerprint recognition. Fast and reliable. 2. Seems to hold charge for reasonable duration. I've had for 3 months and have used it multiple times daily, and have not needed to recharge it. 3. Multiple ways to unlock; Many other locks may only have finger print recognition. Like that you can you Bluetooth or emergency morse code. 4. App is easy to use; has nice log of user access 5. Looks/feels durable. Appealing appearance.
