Lewmar portlights

[srt]

I am looking to replace the lenses in my Lewmar old version size 1 opening portlights, the existing lenses are crazed and difficult to see through. I am considering replacement lenses from Hadlow Marine in UK. Has anyone used their replacement lenses and can give positive feedback? I am in Fremantle West Australia, and have 9 lenses to replace which is very expensive to do locally.
