Negative Positive
Title: Good product, but an expensive accessory.
Review: This product is a must if you use your GPS in your car. It will save you many, many batteries. I like the quality. It feels solid. The LED on the lighter plug is useful. It indicates that you have power. The piece that snaps into the eTrex seems to connect well. It's never come unplugged after rolling around in my truck. The cord is plenty long for my needs--about four feet. My only complaint is the cost. The price was a little more than I would liked to have spent, but it's the only game in town.
