Review: Attention Women: You can do this by yourself, AND they are beautiful! - I am very happy with the quality and ease of installation of these solar lights. I am a 77-yr old senior woman and was able to install these all by myself (after watching a couple of the videos provided). They are modern looking and beautiful when then they come on and I had no issues or problems (other than figuring out how to back the drill bit out of the hole, DUH!) I just put them up yesterday and they all came on last night when it got dark (YAY! projects don't always go so easily or flawlessly in my experience : ) and I highly recommend this product!!
