The NHS ones are pretty basic and you need to change the batteries very
often according to friends of mine. If you want proper digitally tailored
ones than the price is almost anything you can think of. Like you i don't
know why, as the tech is not new and in my view its another thing like
glasses frames disability aids etc, that cost twice as much plus what you
can get away with, using the small market excuse for the profit made.

Your friends are wrong, the NHS ones are digital and are tailored to the
user and the batteries last for a week or two. The batteries are also free.
