MFI are great for basic Kitchens but having bought wardrobes and bedroom furniture from them in the past, I would be very reluctant to do so again. They generally dont survive a house move, sertainly not two!!
Once you have parted with your money you are on your own!
We had a problem with a worktop, and they basically called me a liar when I told them of the problem. They did after several weeks send out a man to see what we were 'kicking off about' and he left us saying that he agreed with us and that we should be entitled to a replacement. He reported back to Head Office and 10yrs down the line we are still waiting!! Keep well clear.
