You've got nowt to lose with the free NHS hearing aids, Jon, honest. They are not bog-standard, you can connect them to your phone via Bluetooth, they are set up for your particular hearing loss, if they go bust they are replaced for free and the batteries and tubes are free forever. If you don't like 'em you can put 'em in a drawer and shop around for the private three-grand jobs, or just not bother. I've had free NHS aids now for eleven years. They're, well, not great maybe, but they're a massive improvement on not having them. Go for it!
