I use Resound hearing aids that I purchased about 6 years ago. I have severe Tinnitius in both ears. I would give Resound a 6 rating on a scale from 1 - 10. I discovered after a few years that the software had been upgraded but the customer must purchase a new pair in order to get the enhancements. I think that is criminal to force a customer to purchase all new hearing aids. It's like requiring a person to purchase a new computer for every software upgrade - it's just not fair. BTW I paid over $6,000 6 years ago - I shutter to think what the price is for a new pair. To be fair they work fairly well and the Resounds do improve my hearing. I am going to test the new Opticon hearing aids due to a rave review from a friend that suffers from Tinnitus as well and was a former Resound customer.
