No good Every button I pushed came back saying file not found, does absolutely nothing! Refund my money, or fix app. But don't sell a product that doesn't work.
Good but not great Would get 5 stars if it had more common formulas like tank volume.
Links don't work anymore Links to resources and website haven't worked since website update.
Very useful app The calculators are very useful and I love getting access to the on-line resource center. The news feed is a nice extra too.
It installed for about 16 hours and I cannot stop it for a refund By then I had made my own calculator. Not worth free it seems.
