Query: 4 stars - nothing is perfect.. but no problems

This is a pretty simple product. If you have the product number right I would say you are all set. BE CAREFUL- I would recommend buying this specific product, it is not your everyday 12v adapter. There are electronics inside that are not inherent to the typical 12v adapter.All in all - I am totally satisfied.
