Reliable with a Loud Alarm
The lock works great and the alarm is very loud, which is perfect for our warehouse. The only downside is that the alarm volume might be too intense for quieter indoor spaces. Installation was straightforward with the right tools.

Good Lock but Needs Battery Care
The lock itself is very secure, but you have to remember to change the batteries regularly to keep the alarm working. If you forget, the alarm won’t function which can be a security risk. Overall, a good product if maintained well.
