This is a great smart lock very easy to install, program and manage. I have purchased 5 locks and I am very satisfied with the purchase. Also if you ever need customer support they are very helpful, quick respondents and professional.

Bought this door knob 2 times during a period of 2 weeks. The first one ordered had the ribbon cable connection broken and therefore could not be installed. I returned it and had a replacement on the way. The second one was perfect, everything worked properly. I am very pleased in terms of how easy it is to set up via the app, adding and removing team members. We bought this for our business for a low security entry way. This lock is used 20+ times daily and will see the effects on the batteries.

This lock is great. Just love it. Easy to install nicely packed.Customer service is excellent with prompt answers and solutions.

I was impressed with this lock at the start, but it started going down hill quick. 3months in I noticed it would randomly be talking when no one was interacting with it. Then the private lock would kick on without the switch on resulting with the only way to open was with the phone. Now it says its unlocked but the outside handle won't engage so its become useless.

Excelente cerradura. La tengo instalada en 2 puertas de oficina. Tuve un problema cuando se averió el sistema que abre una de las puertas. Le escribi a Harfo enviando un video con el problema. Ann Wang me envió una nueva cerradura. Me respondieron rapidamente.

I had an older model that worked for about 2 years. The entire time I could only get the fingerprint scanning to work about 15% of the time, and the unit finally just failed open. The electronics made all the right noises but the lock was completely disengaged. This time I can tell the construction is MUCH more solid, and the fingerprint scanning is FLAWLESS. The TT mobile app works well and is easy to set up. I highly recommend this item. And quite honestly, that’s the first time I’ve said that about ANY Amazon purchase. If you buy it, you will be very happy with this unit.

Mechanically, the door does not consistently open when unlocked. The internal mechanism seems to be damaged. The lock has only been installed for a month. DO NOT PURCHASE.Update:The vendor replaced the broken lock free of charge after I'd like a negative review. After reading more reviews it seems the lock fails everyone after 6 months to 12 months. Although the lock has great features, connects to my Wi-Fi Hub so that I can work with it from home and get notifications anywhere, I am concerned that the lock will fail again. Overall it's a great device that needs to be mechanically more sound.
