So instructions were clear though it should've been more specific about the small wire setup since I build and work PC's/electronics and I also had to figure out my self that it could fit in that small slit other than that it was not a big deal though you should be very careful and I suggest using a headband flash light while setting up this door handle also It should be noted that it does not have internal rechargeable batteries I did not know that so I had to run to the store and get some so be aware that you may need to replace batteries every so often. Setup process was easy download app then from the app you are able to setup the fingerprint also some of the features in the app should be more user friendly like when you press on certain options it will let you press close/open and say started which was confusing me I believe it should be a check box to enable/disable certain features but for the most part there was no issues what so ever.I installed the door handle, which went relatively easy and it seems pretty solid minus the fact that I wish it came with longer latch screws for more security. I went to download the app (which was the most important feature to me) and it doesn't work. It asks me to create an account by entering my email and creating a password. It then asks to enter the verification code, at which time I select "verify." Once I hit verify, the screen flashes and some Chinese text then pops up. I had to translate the text to figure out what it says and the only translation comes up as "failed." I've tried this on both my android and apple devices. There has been no verification codes sent to my email, therefore I cannot access the app and it's useless since I can't add my fingerprint. I will likely be ordering a different model unless this issue can be fixed.Edit: the app seems to have been down at the time I initially tried to set it up. A couple of days later it was back online and has seemed to have been fine ever since.Easy to install and easy to unlock with the phone and key, finger print works but it does bug out every now and again however not to the point where it’s gonna lock you out, door handle feels premium and not cheap, only thing that I would recommend is buying rechargeable batteriesThis is amazing. I order four for my new house and I couldn’t be happier. Easy to set up, install, get the app working and the fingerprints set in. Very happy with this purchaseSimple, functional, easy to use. I ordered the matte black version. However the face plates were not matte black, nor their screws, but not a deal breaker for me personally. The app seems to be user friendly, intuitive, and was also a simple process.I like the product but sometimes the handle although being unlocked, doesn’t open the door unless it’s pushed up instead of downFront door entrance. Secondary lock to my debolt fingerprint lock. Extra assurance.
