Seems to work great but the discrimination said satin nickel under color choice. It’s black satin which is shoved at the bottom of the tile of the product. This is amazons fault. ??I bought this lock a little over a year ago and about 9 month's after buying it, it started beeping all the time. I was a little lazy for a few month's and decided to finally return it. When I finally looked up my purchase date, it was one day after the purchase date. After I wrote the company, Davis from customer service contacted me, and told me he would put the request in, even though it was a day past the warranty. Within a couple of weeks I got a brand new lock! I just want to thank him and the company for the quick response, and giving me a ne lock! I really like the look of the lock and the ease of the finger print to open it. ThanksNo me gusto que usa baterias.We keep losing our carport door key and that is our main entrance. Problem solved with this smart door lock, fingerprint electronic deadbolt and door lock. Comes with keyless entry featuring auto-locking, smart door lock. My wife even got it to work with amazon Alexa.We struggled with this especially when going out of town and having a house sitter, never seem to find a key. This solved it, you can unlock/lock your door remotely, or just use your voice control with Alexa.It also works with your smart phone; we have iPhone but that is cool now we can lock/unlock our deadbolt on the way in or out. or from a far. We have 7 rental properties and are thinking of putting this perfect virtual key solution into all of them giving us access if need or when we turn them over. to visitors.Here is the coolest feature it is a 5-in-1 keyless entry smart lock with multiple ways to unlock your door: smart phone, keypad, fingerprint, ic cards and mechanical keys.What else needs to be said perfect, oh it was very easy to install even I did it with the instructions.The good is the features for the price. You can unlock by codes, prints, key, Bluetooth and wireless (via add-on device). Overall I'd say the lock is adequate but not great. The print scanner struggles with my 6 year old. Does fine with bigger fingers and adults. The keys are basically useless. They are behind a door that I can't open without a pry tool. Maybe meant as a last resort if batteries die? Those keys are also strange and I wonder if possible to rekey to match existing locks.The install was a pain. A tip: I don't feel the top hole is necessary. The bottom 2 hold it securely and then you don't have a non standard hole in your door in case you don't like the lock. Plus if you do decide the hole is needed for stability, the secured backplate makes for a better template.The instructions are a problem. The diagrams for Right or Left swing doors are inconsistent and caused me problems. The diagrams that show an open door are wrong. Be prepared for trial and error which sucks when the wire harness won't come off without a pry tool handy. Took me a few tries.Trying to reuse my original dead bolt inners caused me fits. I wanted the attached plate's finish to match (why have a silver plate with a bronze lock?). Even though the parts look identical the old unit needed more torque than the lock gives. Lesson learned and had to fully dissasemble again.Lock company is in China and so is customer service by email and 24hrs response time as they have 15hr time difference to West coast USA. Written English is very poor and wrong grammar used. Product is the right size and not bulky, looks good but the slide bolt is made poorly with it sitting retracted in an angle (poor design tolerance when made). Instructions , manual and Videos are poorly done and English is poor and many steps to installing this lock are not discussed at all?? The customer service does try to help, but understanding each other is very difficult. Just installed it yesterday and still cannot get the Fingerprint to work all the time?? all other functions so far seem to be working at this moment. Time will tell. Took all day trying to figure how to install and program with the APP and no instructions for programing. As a Note... if you want remote access you have to buy a Gateway separately from another company, another $33.00 to $39.00.bought this with one purpose. to wirelessly connect to my google home and it does not do that. very disappointed in this product. do not reccomend
