After having used this deadbolt lock for about two months now (see below for 5-2021 update), I can share with you I am totally satisfied with it. After shopping dozens of different keyless deadbolts, ranging in price from just over $50 to well over $350, I settled on this one, in the bottom of the price range. Why? 1. I don't trust the security of my personal information in the cloud - there have been far too many data breaches of supposedly "Secure" companies that expose untold quantities of data to hackers. This means I really don't want a lock that interfaces with the cloud. (Internet.) 2. The more expensive locks offer thousands of different entry codes. I only need about three or four. This one offers ten. Plenty for me. 3. The more expensive locks offer the ability to interface with your phone, and lock or unlock your door remotely. I cannot think of a single instance when I would need or use this feature, and so I'm not willing to pay more to have it. 4. This lock offers one-time-use codes, as well as optional auto-lock after a period of time I can set. I don't currently need either of those, but I might, and I am not paying extra to get them. 5. This lock offers the ability to program entry codes up to 10 digits. Four digits is too insecure for me, so I'm glad I can use more. 6. There is a one-button push to lock feature. I didn't realize how much of a plus this was until last month when I went to an AirBnB that had a pushbutton lock that you had to enter the code to LOCK it as well as unlock it. That was a pain. DRAWBACKS: There are only five code buttons. This means the code for 2-4-6-8-0 uses the same buttons as 1-3-5-7-9. This reduces the security of the lock somewhat, but I knew this before I bought it, and with the very low risk where I live I deemed it NOT to be a problem. Especially if I program longer-than-4-digit codes. There IS a light that comes on, lighting the buttons from the inside, when you push the first button - very good for night time entry especially for someone who is unfamiliar with the lock. However, it's only moderate brightness and the buttons are not large, so this might not be enough for some older people or those with vision challenges. However, the buttons are arranged in a distinctive pattern, and it is easy to find your first button by feel, and actually to enter your entire code by feel. Moderately obscure programming. There is small chance I will remember the code programming how-to the next time I need to do it. But the VERY SMALL PRINT instructions are easily followed. Just don't lose your instruction micro-manual. And keep a magnifying glass handy to read it. No word on battery life yet. After two months, the initial set of batteries is still going strong. Overall, this lock rates five stars. If I ever need another one, I'll probably buy this brand again. ========= UPDATE - 19 Months Later ============== This lock still gets FIVE STARS in my book. After about 19 months of flawless operation, I finally had to replace the first set of batteries. Needless to say, I had LOST my micro-print manual, but it was easy to find the PDF version of the manual online. Because I had replaced the batteries, I had to re-program the whole thing. Since I had only changed the master code and entered 3 user codes, this was not that big a deal, but I can see if you had a dozen or more user codes, reprogramming could be a pain in the patoot. In the reprogramming, I ran into a problem - one that wasn't covered in the manual. So I called the toll-free number (in the manual), and with a minimal journey through voice menu purgatory, I actually got a LIVE PERSON who was friendly and knowledgeable, and had my problem fixed quickly. (It turns out I needed to take out the batteries, push all the buttons, re-install the batteries, and start over, then all was well.) This was OUTSTANDING customer service, and reinforces my very strong 5-star rating for this device.
