Query: Battery minder

I purchased one of these about 1 year ago. I've used it over the past winter as a battery trickle charger for a vehicle that I use rarely, and it did an excellent job of keeping the battery charged. I placed this panel in a temporary position so that the sun only landed on it each afternoon, but that was sufficient for what I was trying to accomplish. This season, I'll do something different with mounting and wiring in order to make it a more permanent addition to my garage. I did read the previous reviews here and did also find that the packaging and shipping was perhaps a bit weak; however, my panel arrived in perfect shape and has worked reliably since.
