First, I like this product despite the following criticisms. I just want people to know the negatives when considering the purchase. This unit was used in a protected exterior application. The door in question is a side door that's used a lot, so people tend to come and go quickly, which led to it being unlocked one evening and then somebody came in and swiped some stuff. This unit has fixed that problem, and is very convenient to use. To date the weather's been warm; I'm hoping the performance will continue to be as good when the weather turns cold.

PROS:
1) The fingerprint reader is accurate and fast. Basically it takes less than 5 seconds to open the door and is way more convenient than fiddling with keys.
2) It stores 100 fingerprints, which is great since we have family nearby that we wanted to give access to and this eliminates the need to hand out a bunch of keys that they might lose. Moreover, it permits us to put in multiple fingers for the same person so it can be used when one hand's otherwise occupied.
3) The outer case for the lock is solid - looks like it would hold up to casual attempts to break it.
4) It's convenient to add and delete new people - really handy when you have overnight visitors and you want to give them access for just a night.

CONS:
1) The latch on the first unit we got fell apart and we had to send it back for replacement. The vendor handled it without any quibbles, but it's still odd that something as proven as a latch would fail while the high-tech gizmos worked flawlessly.
2) It REALLY helps to watch the installation videos so you can see the calibration points that are stamped on the inside of the doorknob. They're mighty small and I couldn't tell which stampings the instructions were referring to without a picture. Go to trinity788.com for the info (they don't tell you that in the packing).
3) The fingerprint reader is persnickety. I'm sure it's the flipside of it being accurate and not letting just anybody in, but you'll have to remember the exact finger location and orientation that you used when your fingerprint (or thumbprint) was registered. BTW - the unit's set up makes thumbprints more convenient. Not a problem, just a comment.
4) The unit's too tall to fit in the traditional lower location in doors with predrilled doorknob and deadbolt holes, so you'll have to mount the unit in the upper hole. I wish the manufactures could have designed around this.
5) Be forewarned that you'll have to drill an additional 3/8" hole in the door. This hole is required to keep the unit vertical. Not a big deal, but some people care.

Overall, it's working great and is quite a cool gadget - it's a great conversational item.

I installed this to keep our very precocious and mischievous 3 year old out of a couple of rooms in our house.

Pros: Easy to install, works flawlessly, very sturdy and has lots of backup access in case something does go awry.

Cons: You will have to drill a single hole in the door for one of the bolts. This really isn't a big deal, but if you decide to replace it with a regular doorknob later, you'll have a hole in the door to patch. Indoor use only. It states it clearly on the package. Again, not a big deal, but you should be aware before you buy.

So far, I love it!!!! and now my son cannot get into the room where we keep medicine and cleaning supplies. We are going to purchase a couple more!

We have purchased several of this lock to use at our retail locations. They work wonderfully with one exception. We relocated one of our stores, and when I removed the functional lock then tried to re-install at our new location, the lock stopped functioning.
If you will be moving the lock, you may as well buy multiple ones. They work fantastic provided you install it once and leave it where you initially put it.

Ive already owned this product for 2 years and decided to buy another one for another room.. Works Great! never had a real problem with it

What a Great product. Easy to install. You can program so many finger prints and delete them at any time. Everyone has a specific code so you always know who's coming in. Door auto locks when you leave. Love it!

No more forgotten keys!! This is the best investment I have made in a long time. Easy to install and configure. Works flawlessly 95% of the time. The other 5% is when it is raining and there is water on the lense (resolved by drying the lense and finger) or when there is strong sunlight shining on the lense (resolved by covering the lense with your other hand)

Great door lock and it is so fast at recognizing your finger print. Ive had it on my office door for 3 months now and use it several times a day and its perfect. My only complaint would be the installation, not for an average joe, but not to bad.

Don't throw your money away! I bought this lock 6 months ago... it has locked me out more than I have ever done in my entire lifetime! I called the place I bought it from... they no longer have a rep. working there to help. I emailed Adel themselves, they said they couldn't help me, contact the place I bought it from.

All I get is a low voltage error message... replace the batteries and re-set it several times. It works for about 2 minutes after getting fresh batteries then back to a low voltage error... No one wants to help and the company DOES NOT show interest in backing their product.

this lock is much improved on the older version it has the ability to remove users.

I have one of these on the door leading to my company's datacenter. It feels well built and has not had any problems. I didn't install it (yay for maintenance staff) but it didn't look all that difficult to install. It almost always accepts my fingerprint and it's forgiving enough that your finger doesn't have to be positioned exactly perfect. At the same time it has not yet given a single false positive. The glass on the scanner does need to be wiped clean every now and then but that's hardly a huge deal.

My only complaint is with the PIN code feature. You can program it with a single six digit PIN code (no multiple codes) in case you need to give someone access and haven't yet enrolled their biometrics. However, setting and entering the PIN code is convoluted without a numpad, and the display on the screen makes it confusing.

So let's say you have a PIN of 654321. To enter the first digit you press the + and - buttons until you have chosen the correct number. The screen will show "6-". Then you press # to move on to the next digit, and after choosing the correct number the screen will show "65". Then you press # and the display changes to "5-", then "54", then "4-", and so on. After thinking about it I can understand the logic behind it, but seeing it for the first time is confusing and makes you second-guess whether you're entering the correct numbers.

Having said that, I so rarely use the PIN feature that it doesn't bother me, and clearly the lock's bread and butter is reading fingerprints and the PIN code is a throw-in feature that is useful in the occasional unexpected circumstance. It excels at what it was designed for, so it's hard to hold the PIN shortcomings against it. I highly recommend this lock.
