The SmartKnob for my bedroom door has transformed my home security and convenience. The installation process was straightforward, fitting seamlessly into my existing setup. One of the standout features is the keyless entry. I can easily unlock the door using my smartphone, eliminating the need for traditional keys. The biometric option is also a great addition, allowing for quick access without fumbling for devices. The SmartKnob integrates smoothly with my smart home system, enabling me to monitor access remotely. I appreciate receiving notifications whenever someone enters or exits, adding an extra layer of security. Design-wise, it looks sleek and modern, complementing my bedroom decor. The durability is impressive, and it feels robust and reliable. Overall, I highly recommend the SmartKnob for anyone looking to enhance their bedroom's security and convenience. It’s a stylish, practical upgrade that I wouldn’t want to live without.

Play Video I purchased this knob to protect some personal items in my office; it works great! I was nervous because some of the reviews complained about the functionality of the locking function. The knob was very easy to install (just like any other doorknob) and there is a lock on the inside so the door can be locked from the person on the inside (just like a regular knob). I was also afraid that the knob would be weak or flimsy/breakable but it is so sturdy and strong! The only trouble I had was with the app - it's a little tricky to get to sync the device and then I wanted to add my spouse and that was also not-simple but I figured it out. (My recommendation is to install the knob before syncing to the app). Once the app is set up and you add the fingerprints, you don't need to fuss with the app anymore. The app allows you to unlock the knob with a swipe-button and keeps a log of who unlocked the door. I turned off the knob beep with the app, as well. I also tested the knob by deleting the app and the knob still worked; it also works without WiFi or when the power is out. The battery life on this knob is SO good; I've only charged it once since I installed it (four months ago). The kit comes with a key to unlock the knob (just in case) but haven't had to use it at all. It’s very easy to charge and it charges quickly. I think the only thing that could use improvement is the app. I am happy with this purchase and the price seemed very reasonable to me. I would purchase another one and have recommended this lock to friends and family. This lock does everything I needed and I am very satisfied.

This truly came in very handy and we are really happy that we decided to buy this. It was pretty easy to install, works well, and it has been 4 months without needing a charge so far. Only thing is that the remote unlocking feature via the app only works if you're in Bluetooth distance. However that's not why we bought it so no big deal. We decided to purchase another one just last week so we are definitely fans.

Delivery was quick, product came as advertised. Door lock is great quality and easy to install. It was easy to program and works great! This is great peace of mind for some added security to the door for my college dorm room.

Overall, I am pleased with the door handle. We have a consistent stream of visitors in our house and this makes it really easy to ensure they stay out of our bedroom while giving us easy access. Setup was confusing with two users on two separate devices, but after 24 hours everything seemed to sync up okay. One charge has lasted months, and the recharge was very fast. The biggest issue is that if our fingers get too wet (shower/swimming/cleaning) then it doesn’t read our finger prints so we either have to have our phones or a spare key handy. It does, however, read better than most other finger print devices I’ve used.

I’m blown away by the Smart Knob! This fingerprint door lock is a game-changer. Setup was a breeze, and the instructions were clear. The biometric feature works flawlessly—no more fumbling for keys or worrying about getting locked out. It recognizes my fingerprint almost instantly, and the app control adds another level of convenience. I also love that it offers multiple unlocking options: fingerprint, app, and a backup key. It’s perfect for bedrooms, front doors, or even the office. The sleek design fits well with my home decor, and the build feels sturdy and reliable. If you're looking for a modern, keyless solution that combines security and convenience, this is it. Highly recommend!

I love this product. A friend of mine suggested I purchase this doorknob because I was always complaining about people coming in my room when I wasn’t home. One or the best product I’ve purchased this year. I give this product a 10 out of 10 highly recommend. You can use a key your phone or your fingerprint to gain entry.

I bought one to keep my kids out of my bedroom. It worked well enough that my elderly dad bought one for his room too. We are now buying them for the other bedrooms and the pantry in the house. They work super well, easy to set up, and reliable. The quality is there as well. They sometimes do glitch out if you put your thumb on the device and it unlocks and you go to open it too fast. We’ve had our first one for 2 months and still haven’t had to charge it. It’s worth it!
