Most important question. Do you like the dr / audioligist?

If no, you will never be happy with your aids.

If yes, you likely will be.

There are dozens of brands, but only about four or five manufacturers. So the tech is the same in the various brands. The diff is marketing and customer service. (There is a difference between the lowest price and highest price within a brand too.)

Having said that, if you are price conscious - you can get similar aids for less, but you won't be happy unless you like the dr well enough to work with them to make the adjustments.
