We have just purchased a home with a Magnet kitchen already installed. It has not withstood the test of time by any measure - utter rubbish!
The previous owner left all of the paperwork and it shows the kitchen is 7 years old and cost around 3300 - the same as my current Nolte kitchen. In comparison, the quality of the Magnet units are entirely inferior (doors delaminated, unit shelves too thin/weak (bowed), etc) and the installation is similarly poor, with many gaps between the units and walls/floors and the like.
Bottom line: I will be removing the Magnet and I will replace it with my 7 year old Nolte.
