Here is a product that is focused like a laser beam on aspiring law students - the 180Watch. It's an analog watch with stopwatch capability and highights at thirty and thirty-five minutes.
I don't claim to fully to grasp the issues here, but the target market is people about to take the LSAT, and I do note this in the testing rules:
Items Allowed on the Desktop
Test takers may only have tissues, ID, wooden pencils, erasers, a pencil sharpener, a highlighter, and an analog (nondigital) wristwatch. No electronic devices are permitted. Neither are timers of any kind except analog wristwatches.
Wow - what time is it? Time to take the LSAT! There may be an app for it but you can't have your smartphone anywhere in sight. And my cheap twenty dollar digitial watch would also get the boot (but not my cheaper Fauxlex).
Well. We applaud the entrepeneurial spirit behind this design, not to mention the aggressive attitude that pushes to the edge of the rulebook. Law school, ho!
