Let me start by saying, these Lanwandeng door knobs are a solid choice if you're looking for an affordable way to upgrade your interior doors. I installed them in my home's bedrooms and bathrooms, and overall, I'm pretty impressed.

The matte black finish gives a modern, sleek look that blends well with most decors. Installation was surprisingly easy - even for someone who's not super handy. The package includes everything you need, including a scratch-resistant screwdriver (nice touch!).

One thing I really appreciate is the adjustable latch system. It accommodated all my doors perfectly, whether they were standard thickness or slightly thicker. The mechanism feels sturdy when operating it daily.

However, there's one important caveat: don't overtighten the screws! Like one reviewer mentioned, I made this mistake initially and the knob wouldn't operate smoothly. After loosening them slightly, everything worked perfectly.

The privacy function works as expected in most cases - great for bathrooms or kids' rooms where you want some privacy without keys. That said, I did notice that on one unit the locking mechanism wasn't as reliable as the others.

For the price (especially considering you get six knobs), these are excellent value. They're not premium-grade hardware, but they definitely exceed expectations for budget-friendly options. Just be sure to test each one thoroughly after installation.
