Makes understanding the periodic table fun and easy to remember. Love the way the concepts are well explained and can be understood by anyone whether the person has detailed knowledge of chemistry or not. Would highly recommend.
The case is very good looking - total value for money. Just one thing I felt was not upto the mark was the volume button on the phone keeps pressing on its own because the case is too tight around that area ... could have been better designed to take care of the phone's buttons. Otherwise a great product.
