The deadbolt flex pins installed nicely, but I haven't been able to try them out yet as my preamplifier is still in the shop. I am looking forward to having my system up and running soon.
My package was damaged (envelope delivered empty) and one day after I contacted them, they had a replacement in route.....even before I could send more details on shipment. The plugs themselves are also great, high quality, firm fit inside my receiver jacks, couldn't be happier!
