I wanted something to put on my wall and I saw this ad on facebook. I had never seen anything like it so I gave it a try. I cannot stress enough how satisfied I am of my purchase. Just look at the picture, it's absolutely amazing. Super easy to install and everybody that comes into my house wants to turn it around and is baffled by this. The fact that it changes every single time is just so unique. Sometimes I reset it and the next day the sand is still flowing. I could gaze at it for hours straight. Sometimes I feel like hearing the grains of sand tumble down could be even more relaxing. Anyways, fantastic purchase, do not hesitate to get your hands on these, it's even prettier in real life.
