I originally bought a few sets of these at Sam's when I was in the store in the spring. When I finally put them in my front yard, I realized how awesome they were and tried to get more ... but, unfortunately, Sam's was sold out at that point. Luckily, Amazon came through and had some in stock. These are hands down the best solar lights I have ever purchased (and I've bought many over the years). The brightness is stunning and since they lay flat on the ground you don't have to bother with straightening them all the time like you do with the above ground lantern-type solar lights. My front yard looks great because of these little gems. Highly recommend!!!
