Very solid product and quiet!
Quiet! So many of these locks are freaking loud and this one is very subtle by comparison. Love that you just walk out the door without unlocking and can have a silent mode when pushing buttons outside. Workings are smooth, unit is nice weight and quality. Installed in 10 minutes.

Great lock so far!
The media could not be loaded. Just got this digital lock and so far I’m really impressed! It was easy to set up, works smoothly and being a mother it gives me real peace of mind knowing the house is more secure. I love not having to worry about carrying keys around anymore.It feels sturdy and reliable for the price and it’s honestly a great deal. We’ve only had it a short time but everything is working perfectly. Hoping it holds up long term but for now we’re super happy with it!

Overall quality of the product
The value for the money is good. It can be installed easily in place of standard door locks. Programming is not complicated. I m not sure how long the battery could last. If it lasts for a year I could add one more star to my review. Until then I giving it a 4 star.

Easy to Install and Look Fantastic!
I’m thrilled with this product. Super easy to install and works flawlessly! I looked at other brands and you get four for the price of one of the “name brands”. They’re stylish and chic, look great on the door! All four are not keyed the same with the physical keys, but we gave one to our son, so it worked out fine.

Great Value
This has been a surprisingly good product, easy to install, has handled the Florida weather conditions well, its been in place for months now, no issues as of yet... however, be aware that if you have a deadbolt right above the doorknob you could have issues with the keyboard entry fitting correctly with a deadbolt that also has a keyless keyboard entry.

Sleek, Secure, and Incredibly Convenient
I’ve installed several smart locks over the years, and this HIDALIFE touchscreen model is easily one of the best I’ve used. It offers a great combination of security, ease of use, and modern design—all at an affordable price.🔒 Reliable Keyless AccessThe anti-peep touchscreen keypad works beautifully and allows for up to 9 user codes—perfect for family, guests, or even rental management (as suggested on page 3). I love not having to fumble for keys anymore.🛠️ Smooth Installation and FitInstallation was a breeze. According to the product specs on page 1, it fits standard 2-1/8” door holes and supports both 2-3/8” and 2-3/4” backsets. I had it installed in under 15 minutes, and it aligned well with existing door hardware .💪 Solid Build with Modern LookThe “Solid and Durable” infographic on page 2 reassures with impressive specs: 250,000 usage cycles, salt spray resistance, and ANSI Grade 2 latch. The matte black finish looks sharp and resists fingerprints.🚪 Versatile for Any Entry PointWhether you’re using it for an apartment, front door, office, or garage, it adapts well. I also appreciate the backup key option, just in case.✅ Pros:Responsive, anti-peep touchscreenStores multiple passcodesStrong zinc alloy constructionQuick, simple installationGreat price for the feature set❌ Cons:Batteries not included (minor gripe)Overall:This lock is a fantastic upgrade for any door. It looks modern, works flawlessly, and adds a real layer of convenience and peace of mind. Highly recommended!

Great Door Knobs!
These door knobs are well made and function exactly as they are supposed to. Took about 10 minutes to install start to finish. For the existing holes in our doors perfectly.
