Don't get too excited about that no hassel returns claim. I ordered one set, cheapest analog. Didn't help my mother at all. Called to return and they upsold me the next model FOR NO ADDITIONAL CHARGE! (That was unexpected!) Sounded like a deal. Got those and they did not help her either. Turns out her hearing loss is too profound at this point. So I called to get an RMA to return them for a refund. Took several emails, and several people to finally get a code. Meanwhile the 45 day clock is ticking. I am still waiting for them to confirm receipt of the aids and then I must wait until they confirm they are in good order and complete. Who knows if Mom will ever get her money back. My advice, if you are already wearing hearing aids and know you have severe loss, don't do it.
