Richard,

I have no idea what a good router bit should cost you in the UK. I pay ~$25
delivered for my 3/4" round over bits and they are of so-so quality. From the
picture and the price these are bottom end bits with no kick-back protection.
But for a one-time project, if you don't force it, it should be OK. Now if you
want real top quality bits, the Italian Freud products are it.

The 19.1mm cut radius is bit bigger that 3/4" -- .05mm to be exact, but who
cares! That's just rounding error. Assuming that you used 18mm or 19mm material,
all should be well. I suspect that this is a Chinese product made for the US
market.

use it once so it's not worth spending too much. I might be able to borrow a
1/2" router!
