    Works great as Swann camera replacement. The cameras started getting a ghosting pattern. The power supply was weak. I couldn't find any help online to solve the problem. This was the fix.

    I Made thousands of dollars on a $6.99 investment

    This product saved me thousands of dollars! I work from home and I was in another state caring for my Aging parents and in the middle of my shift my monitor just stopped! So I immediately thought about the Geek Squad, well they had several other people in front of me , I thought let’s see if I could buy a new power source, it was the only one left in the store and it was an open box, $6.99 and I was able to work those two weeks away from my home and still support my family! Love it!

    Our security system quit working because of the power supply transformer. Purchased this one and everything is working as it should again. Met my system requirements. I’ve had it a few months and it’s working great.

    I needed a replacement power supply for my home security DVR and this worked and continues to work as needed. Make sure you see what amp rating you need for your device, before purchasing.

    Pin Size Missing In Description

    The product itself is fine, and the cord felt good quality. However, it didn't fit my device. Nowhere on the product or in the description or specifications does it say it is a 5.5mm pin. It did mention "Compatible Platform(s): Universal" which led to me to believe it was a universal adapter of sorts. I was disappointed that the description was not detailed enough to make an informed online purchase, and I had to return it. The automated chat also assured me it would fit my device, when I told her the brand and model number of the device I would be using it with.

    The power supply to our security system died. So I checked the specs and this one fit the bill perfectly. It's been a few weeks and so far it's worked flawlessly.

    Need for older items that use 12V. Sometimes it’s good to have a spare adapter for something you might have to replace but can’t find online, like a router power adapter. I suggest checking out your inventory and identifying which ones might need a replacement.

    So, I can't possibly rate this product appropriately given it doesn't work with my older Bose Sound Machine, but that's not the fault of the Bose or the Power Supply, it just doesn't work with the intended "recipient" and to be clear, neither party suggested it would. I'm sure it works fine on other products, I just took a shot in the dark and missed on this one.
