Fitting Range

I have looked at the phonak nano and it covers moderate to mildly severe hearing loss. I matched up my loss and I JUST make the range. I am on the border. Now I am thinking is this a good idea to pursue this? Or should one always go for a hearing aid with a bit of “buffer” in terms of range?

When I fit a hearing aid I always try to figure a 5-year lifespan and want to be able to accommodate loss that could potentially occur (expecting that HL is progressive in nature) within that time frame.

So I am never thrilled when a patient wants to buy a hearing aid where their hearing loss is already at the upper limit of the hearing aids capabilities. BUT, if they are aware of the limitations for increases in gain in the future and they still want that hearing aid, it’s their money and their decision.
