Nah that's your Amazon, I have to use the UK's version. There is no Irish one. I tried and I can get that on ebay cheaper. It always seems to be cheaper for me on Ebay, esp when importing from the US which I have to do with most of my stuff(except electrical goods).
That looks like it would work or this one???

You could get yours from HD or Lowes, a lot cheaper. Have read people on here getting them there. I tried that, it doesn't work for me. That plan I had didn't work anyway
