I have bought these tanks for a few years and I love them.  I took off a star because I was expecting the colors shown, not grey, pink and white.  I assumed the 'assorted' in the title meant there were assorted colors in the pack (aqua, dark pink and white), which was clear.  I didn't expect the assorted to mean that the color packs varied.  I did not read the reviews before buying because I was already familiar with the product but others also made reference to this issue.  I ended up returning them because we already had these colors.
