"I ordered a large Ecosphere from MED-Worldwide on 8/10/2010. Although the shipping process was mysterious (no tracking information) I was told that the process would take 5-7 business days and that timeline was correct. My order was delivered on 8/19/2010 via UPS Next Day Air (signature reqd). Contents were intact (amazingly, considering how fragile) and none of the shrimps died! I love my Ecosphere and am very glad I bought it from MED-Worldwide because they had the best price!"
