Review: Consistently good - We had a need to secure several interior doors and wanted a combination door handle that doesn't require a key. I was so pleased with this product that I ordered five and they have all worked consistently well. All my installations were replacements so I was able to save the original strike plate and I didn't have to use the supplied guide to make a strike plate. After figuring out that the assembly required disassembly first I went from 45 minutes on the first install to 10 minutes each. As shown in the photos the unit comes fully assembled and has back-up keys along with a strike plate if needed and templates when boring the door hole. It's very important that the door is the correct size as cited, and to adjust the screws with a manual phillips head and not an electric screwdriver in order to avoid over-screwing. The handle is made from sturdy material and it not likely to break without a lot of effort. The four AA batteries that are not included make the keys light up whenever touched making it easy to enter the combination in minimal light. Finally, it can be set up to use a finger print, which I haven't done. If I have problems doing that I'll update this review, otherwise, my opinion is that the user will be very happy with this product. Each the internal and external knobs extend three inches from the door.
Review: Trust me, buy it. - Installation and programing was an absolute breeze! They literally make this product idiot proof. The instructions are straight to the point and simple. The door knob looks so nice and sleak and most importantly adds great added security. Its a great buy, you get more than your money's worth! The fingerprint recognition works better than any other device I own.

Nice doorknob, easy installation. Programming is fairly straightforward. The instruction book walks you through it. Best part is, they have 3 ways of working the lock. Biometrics, combination and key.
