### ⭐⭐⭐⭐⭐ Nice
*by N***R on February 3, 2026*

Nice looking door knob. Very easy to install. Good weight to it, but not as heavy duty as the name brand I usually get. Great for the price and works well!

### ⭐⭐⭐⭐⭐ Great knobs
*by A***U on February 2, 2026*

These are great and an even better value. They are as easy to install as any door knob and deadbolt set and they look and feel like quality.

### ⭐⭐⭐⭐⭐ Sleek Coastal Entry in Minutes
*by S***H on May 25, 2025*

I just installed these door knob and deadbolt set on my 2 garage doors, and I’m genuinely impressed—especially for the price. The matte-black finish has that modern “coastal” vibe without feeling trendy, and the hardware feels solid and well-made. Effortless Installation: Came with a clear drilling template and all necessary screws; I swapped it out of bold doors in under 20 minutes with just a Phillips head and a flathead screwdriver. The knob turns crisply, and the deadbolt slides in and out with no binding. The keyed lock locks securely and the included keys feel sturdy. Came with 3 keys for each door. If you need a reliable, easy-to-install exterior knob/deadbolt combo that looks great in matte black, this Amazon Basics set is a home-run.
