This looks like a great idea. I have not tried it or talked with dentists who have used it but the concept makes a lot of sense.
The leading cause of digital sensor failure is normal USB wear and tear? Issues like ‘half-images’, ‘grainy images’, ‘undetected exposure’, ‘random disconnects’, ‘hardware errors’, etc – are all likely symptoms of the same underlying issue; the added electrical resistance of a worn USB connector. The average USB connector is only optimal for approximately 300 – 500 re-connections. In a high volume practice, that’s less than 1 year.
