Good benefit to cost trickle charger

I bought this to keep a rarely-driven vehicle fully charged. I’m very happy with the ease of use and effectiveness of the simple to operate device.

Product not as stated

The description of the product on the BetsBuy website is incorrect. It says that the package includes 3 ways to charge the battery: 12v/dc outlet, battery clamps, and ring terminals. I purchased from Best Buy because it says it includes the 12v/dc outlet and I did not want to deal with opening the hood of my car to connect the charger. Well surprise, no 12v/dc outlet attachment included and the box states that it only comes with the battery clamps and ring terminals.
