Thanks for your excellent service and quick delivery. The reason for average experience is that of the product. My sink is only 60mm diameter and this one was 60-65 so I had to chip some off using a blade so it would go in the 60mm. This took me a long time to do. I was looking for 60 but couldn't find any. My issue here is that the product was more for a 65 mm diameter than a 60 mm. Anyway I was able to fix it but took time trouble. Would you know where I can buy a 60mm one. ? Thanks again for your excellent service.
