Review: Well thought out. Meets my requirements - This is a great lock. True, I just installed it today but it is very stout - heavy stainless steel, it has an ability to have digital codes up to 13 digits where the correct number in the correct sequence must be entered. It also allows up to 9 users with different codes. It is very easy and very straightforward when it comes to changing the codes. And the lock is complete with 3 keys in the event there is a need as well as a way to power it externally... which I can't figure a use for but it is there. And if you forget everything, there is a way to reset the system - albeit you have to work a bit to do that. It is relatively easy to install and has rubber type mats designed to go between inside and outside knobs, thus protecting the door and securing the latch from water intrusion. However, the entire inside of the outter lock is covered with a steel plate which in its self makes the unit water resistant. Well thought out and heavy duty ... this system met my needs and then some. You will need 4 AA batteries...
Review: Very nice door lock! - I bought two of these and have installed them both on outside storage closet doors. They look good and both work just as advertised. The directions take a little figuring out for the programming. Kinda written in a backwards manner in places. The installation was great! Easiest combination lock I've put on - and I've done several Schlage models. Extra parts came along with this - including 3 keys and a screwdriver. Downsides? Hmmm, the keypad is not lighted - but not an issue for our location. This lock probably doesn't look quite as upscale as the Schlage model on my front door - but it still looks very good. Bottom line for me was the ease of installation and the perfect functioning of these locks for thirty days now.

### ⭐⭐⭐⭐ Review after Six months of Use ; functional , working as new.
*by D***K on May 6, 2019*

It’s a solid lock for the most part, does what it’s supposed to. I’ve owned this lock for almost 6 months now. I use it every day multiple times a day and still have not had to replace the batteries. So I give it four stars for that reason alone, aside from the basic functions it has. There are no lights To illuminate the keypad so if you don’t I have sufficient lighting it will be a little difficult to use. I recommend looking for another brand of this is a dealbreaker for you. As far as keeping us safe awa I have sufficient lighting it will be a little difficult to use. I recommend looking for another brand if this is a dealbreaker for you. I also do like the fact that the key slot is hidden, not many people walk around with magnets on them so it makes it a little bit difficult to pick this lock . As far as setting the password I never change the original code so I don’t know how easy or difficult it will be to do so. I currently use this lock in my office , no problems so far except that the whole door knob/lock/keypad shift in the direct of which you open it due to how strong the return spring is on the handle ; requiring you to put a decent amount of pressure to turn the knob and open the door. It Could just be the way the door is cut , I can’t say 100%. The lock itself feels heavy seems to be made of high-quality material and very durable. The metal has maintained it shine and brilliance as if I just got it.
