Worked as Intended
Worked exactly as intended. Was able to get into my safe and then change the batteries. Saved me from having to call a locksmith or buy a new safe

Good quality
This item worked exactly as needed. We have a shelf that has a power supply like this however my husband miss placed it and the batteries in the shelf died. This worked perfectly to plug in and get the shelf to open without having to damage it,

Worked like a champ!
Didn’t realize what this was when one came with my safe so threw it inside and wound up locking myself out of it…bought this one and it worked like a champ, opened up my safe to find the manual keys and one of these units…so now I have two. 🤣

Access to Barska safe
Couldn’t find my original key or battery pack. Was able to access my Barska biometric safe to replace the batteries.

Wrong plug, good battery pack.
Battery pack is good but the plug is wrong for my Berska biometric safe....its too small. I'm going to need to cut the plug off and splice the correct size plug onto the wires.
