This thing is very durable and I can take it outside or anywhere! I like the calculator and clock as well as the whole Bible part. It is kind of cool to be able to type in a reference and then while everbody else is still searching, I'm there! People also love asking me if some word is in the Bible and I can use the find function and pull it up in seconds. There is no doubt, if you knew everything this thing could do, you would not hesistate to buy it.
This is a great product that I take with me everywhere I go. Fits in my pocket, easy to read, I love the "FIND" feature when I'm looking for a verse or topic. I bought one for a friend and they love it too.
