Really like it for the convenience of quickly getting on line to check the release, deviate, pairing, etc. The open time function is cool, but man it seriously drains the battery quickly. If you have a block of time you want to be hawking open time, then it is much more mobile then sitting at your computer hitting refresh. Overall well worth the cash for the app. Don't know about the open time cost. It's expensive, but it only has to work once to pay for itself.
