Sturdy Material. Only came with 8 led instead of the 12 that is was supposed to be. Therefore the light doesnt really light up the water like it shows in the picture. Also i got the purple light and it looks more like uv light than purple. but price is still good.
UPDATE: 12/20/13. Customer Service contacted me right away and has resolved my issue. They are amazing!! Definately coming back here for more
