1.0 out of 5 starsThe app to install this is all in Chinese. Not very useful if you can’t read it. Will be return. Lock is ok.

4.0 out of 5 starsThis is a beast of a lock. It is bulky and heavy. It is however impressive and secure.you will need a little patience to set this up however. You will need to install the app, set up the account, set up the finger print. this will take some time and can be a fickle process.Once you have it set up though it will save you time. I don’t use the fingerprint that much but the blue tooth option is pretty cool. Its great for unlocking the bike int he dark and you don’t have to fiddle with entering a code in the dark.

5.0 out of 5 starsThe lock seemingly is an excellent lock and is everything I have come to expect in RockBros Products. First, download the TT Lock App from your applicable APP store. Follow the directions and activate the account. Make sure that the lock is fully charged before attempting to sync via Bluetooth. Make sure your Bluetooth is on and discoverable, push down on fingerprint button on lock and hit the + Add Lock to account and follow instructions on your phone. I chose to add a second lock to my account and named it differently. Once it is sync via Bluetooth, you can add multiple sets of fingerprints as applicable. Key is to make sure the lock is fully charged first. You can rename the locks in settings. Really is a nice lock once you download the app and have a fully charged lock. Good luck, be patient and it’s a good product.

2.0 out of 5 starsNo fingerprint reset. Manufacturer and app developer do not help. Blame each other.

5.0 out of 5 starsLock is very heavy duty, surprised me. Sure nothing is perfect, but I’d feel okay leaving something for a few minutes with this protection.

4.0 out of 5 starsThis is the second of two locks I purchased. The lock itself works great. I find the fingerprint sensor works most of the time, and by “adding” more than one finger or finger orientation is helpful when locked at awjwards angles.I love the Bluetooth functionality and makes it easy. The heavy and durable materials make it difficult for thrieves.The only downside is the app QR codes leads you to a Chinese language app store. It’s almost impossible to navigate for an English speaker and not necessary to get the app. Minus one-star for this foible.Just go to Google play store and look for TT Lock. Don’t waste time on the QR codes. Make sure the lock is fully charged before trying to pair or you may run into difficulties.All in all a high quality and fantastic lock!

5.0 out of 5 starsLet me be the one to review the product. At first, I was hesitant to buy this because no reviews. Software responsive, you can use your fingerprint to unlock it or via the app and key.Downside- too heavy, but at least you can tell it is heavy-duty steel.I bought another brand same design and not as heavy as this one.So far I’m satisfied but hopefully, no bugs with the software, and it will last longer.
