I placed my order at about 11.30pm on a Tuesday and received it in full on Thursday of the same week. Impressive!! I thought that I may have received one incorrect product, although I suspected that it may have simply been branded differently. I quickly queried such and just as quickly received a reply confiming that they were in fact an identical product. So perfect order delivered very promptly. We have only tried one product as most are Xmas gifts for my son. The product tried, Crystal Christmas Tree, performed as expected and my son loved it. As we are so far very impressed with Mad About Science we will take the time to put up our reviews on the many other products when we have trialed them after after Christmas. Thanks Mad About Science!
