Netfloat - any good?

[Coastie]

Hi

I do have problems with both heron's and owls taking my goldfish.  Have got a frame with a net over the top which I keep there from December til around May.  It looks unsightly but does the trick.  I'm now thinking of Netfloat and was wondering if anyone out there has used it.
