Bought 5 of these door handles for Black Friday in 2022. The positives - they look great, and have a solid heavy feel to them. Though there seems to be some quality control issues. Unfortunately, on one of the sets, both crystal knobs fell off during installation -- before even using. Customer service was great and sent a new set. Now, 3 months later, another of the crystal knobs fell off. I am not using the door handle heavily or unusually, and even so, a door handle should be rated for thousands of turns before failure. Not 3 months! Really do want to like these, but at a 40% fail rate so far, I'm wondering if I'm just waiting for the other handles to fail.
