Purchased this item to replace some aging items gotten many years ago.  Wanted some of the same features (namely switchable from "normal" to "multicolored" for Christmastime enjoyment).  So far, very pleased with the performance of these units.  Will see how they stand up to the herd of marauding deer in our neighborhood, who, apparently, can't see much in the dark and several of my old units have been found (snapped from their ground spikes) several feet from where they started....
