hi Alistair,
it's worth taking a look at qvc's own make air fryer, i've had several makes
over the years including tefal, philips, breville, plus some others but the qvc
one i bought about 4 years ago is the best of them.
the controls have changed on the newer model but appear to still be very
accessible.
it's a digital air fryer that is a 2.6 litre capacity and all the buttons beep
when you press them.
my one has all buttons while the newer model also has a dial to set a manual
time.
but from listening to the demonstration video it appears as if even the dial
beeps as you turn it so you could count the beeps to know how many minutes you
are setting it for.
the buttons are for preset cooking times and temperatures for specific foods.
if you visit the below url and play the video you will hear them describing the
use of it with the buttons and dial beeping.
when i went to play the video it had no sound but for some reason the audio is
muted automatically and all i had to do was cursor down and press enter on a
button labelled "unmute".
it normally costs £68 but is on offer for £54.96 plus postage.
here is the url.
