Just bought this for my mum (link below) and it works. Yah. She now has something that she can tell the time with and I think its the yellow face that makes all the difference. So thought I would pass on my excellent find to the lovely people on here - who have given me support and guidance throughout this difficult time - as I know not being able to tell what time of day it was was one of the things that upset my mum.
The postage is quite expensive (nearly £10), so all in all it cost £31.50 including postage, but you do get it delivered the next day.
I hope it works for others on here the way it has worked for my mum.
