The polished brass finish adds a touch of elegance, and integration with our hotel management software was seamless. No more lost keys or lockout calls!"Purchase Date: April 2024 | Usage Period: 8 months

"I replaced all interior door handles in my home with the brushed metal PBT-6521 model. Installation was straightforward thanks to the precise technical drawings. The three-pole lock design feels solid, and I love that it works on both my wooden bedroom doors and metal bathroom doors. It’s modern, secure, and easy to maintain."Purchase Date: January 2025 | Usage Period: 4 months
⭐⭐⭐⭐☆ David Reynolds - Office Building Supervisor
"We chose the Advanced Model for our office suite renovation. The tamper-proof deadbolt and 65mm hole spacing compatibility made it ideal for our mixed-material doors. Staff appreciate the sleek look, and we’ve had zero issues with wear after six months of heavy use. Only downside: the brushed metal finish shows fingerprints, but that’s minor."Purchase Date: September 2024 | Usage Period: 6 months
⭐⭐⭐⭐⭐ Elena Torres - Hospitality Interior Designer

⭐⭐⭐⭐☆ Marcus Lee - Property Maintenance
"Installed the Base Model in 15 units as part of a security upgrade. Durable? Absolutely. The zinc alloy hasn’t corroded, even in humid conditions. Cost-effective for large-scale use, though I wish the code lock had remote reset capability. Still, a solid upgrade from our old plastic handles."Purchase Date: July 2024 | Usage Period: 8 months

Michael Tran - Commercial Access Control Expert
"The PBT-6521 stands out in the mid-tier commercial lock market. Its direct compatibility with hotel management systems, combined with 300 lbs magnetic holding force, makes it a reliable choice for properties transitioning from mechanical to digital access. The zinc alloy body outperforms plastic alternatives in longevity, especially in coastal or humid environments."
Sophia Bennett - Interior & Building Design Consultant
"In my experience, hardware often compromises aesthetics for function. Not with the PBT-6521. Whether it’s the polished brass in a heritage renovation or the brushed metal in a minimalist apartment, it blends form and function. The availability of multiple models allows precise alignment with project budgets and design goals."
