Review: Finally a Door Strike that "Buzzes" !!!! - Operate it with 12VAC (YES "AC") and it buzzes perfectly while opening. Now i truly can "Buzz" in Clients. THe DC Strikes are totally quiet and nobody knows that you activeted it.
Review: Can’t remain energized more than 15 seconds - Nice strike plate lock, but the label on the lock indicates a time limit, and the instructions say the warranty is void if power is applied for more than 15 seconds. Unfortunately this was not in the description of the product. I have a controller that lets me keep doors unlocked during business hours by applying power for hours, so I can’t use this.

### ⭐⭐⭐⭐⭐ Finally a Door Strike that "Buzzes" !!!!

Operate it with 12VAC (YES "AC") and it buzzes perfectly while opening. Now i truly can "Buzz" in Clients. THe DC Strikes are totally quiet and nobody knows that you activeted it.

### ⭐⭐⭐⭐ Can’t remain energized more than 15 seconds
*by W***M on July 7, 2022*

Nice strike plate lock, but the label on the lock indicates a time limit, and the instructions say the warranty is void if power is applied for more than 15 seconds. Unfortunately this was not in the description of the product. I have a controller that lets me keep doors unlocked during business hours by applying power for hours, so I can’t use this.

### ⭐⭐⭐⭐⭐ Works as designed, seems sturdy, time will tell
*by L***S on August 16, 2021*

Item is heavy making it seem robust. Installation was as would be expected. Old lock was slightly off center so we had to chisel a little bit higher up than the prior door strike. Lock doesn't have a lot of give which is nice. Time will tell how well it works and how long it lasts. The one this replaced lasted around 20yrs and had been repaired several times, hopefully we get a similar run with this one.
