I bought this because, in my old age, my fingers are getting stiff and a regular keyboard is just too small. I used to be able to touch type!
The keys are bold and easily found and it is a relief from my old one. I am no longer typing two keys at once!!
Cons: I would have preferred all the keys to be in the same colour say white on green and a different font. They are all lower case (and coloured in zones) and that is ok but the letter L looks like an upright slash and for some reason I found this confusing so I painted a little foot on it.
Not expensive and I am glad I got it.
NOTE: I could not get my computer to detect it (it's USB) until I uninstalled the driver for my old wireless keyboard. Then I had to use some clever tricks to shutdown (since the keyboard was then disabled) and then reboot with this keyboard in the USB port and the wireless dongle removed.
