Bought mine from SGS too, GS14-27-250-300 with 1200N force. Perfect fit.
They did mix up the address: The Italian marina's street address is "Corso Argentina" and tracking showed the item was being shipped to the country Argentina instead of Italy. I contacted SGS and they corrected it in transit, which caused some delays but I eventually received the item.
Apart from the adressing mistake, they were easy to contact, polite and got it sorted out. Quality is good. Probably would use again. Also paid 60 quid with shipping to Italy (before Brexaster).
