Bests & Worsts Reviews from Amazon

I have purchased these in past and loved them. Recently bought another, but it failed to work, even the replacement didnt work. Dealt with LisaMarie c/o seller, who requested I send replacement back so they could investigate. Weeks later, I remain solar rainbowless. Too bad she couldnt have personally sent me one that she witnessed working where crystals werent broken if she cared so much about monitoring negative reviews, but alas, it was not meant to be... Really disappointing.
