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: Exceeded Expectations. A Must-Have for Modern Security! - I purchased the Thorbolt Biometric Doorknob from desertcart without expecting too much, but I was pleasantly surprised, this product truly exceeded all expectations! From unboxing to installation, the entire process was incredibly smooth. The instructions were clear, setup was quick, and programming the fingerprints and codes was surprisingly intuitive. The design and ergonomics of the doorknob are top-notch, it feels solid, looks sleek, and fits perfectly with the existing hardware theme in our home. The finish matched beautifully, almost like it was custom made for our space. Functionality-wise, it’s a game changer. We now have enhanced security and peace of mind, especially knowing our room stays off-limits to the kids when we’re not around. I also love the flexibility of being able to program multiple fingerprints, permanent and temporary access codes, and even one-time use codes, an awesome feature for guests or service providers. This doorknob has added not only security but also a touch of tech-savvy elegance to our home. I’m already planning to purchase additional units for our office and garage door. Highly recommended for anyone looking to upgrade their home security with smart, stylish, and reliable tech. Thorbolt knocked it out of the park with this one!
