I bought this to replace my ageing MFC-5440CN. Build quality is similar, but there are a number of improvements, like not having to open the printer up to for new ink cartridges. Printing is also very fast, and being able to use A3 occasionally and also feed labels in are real benefits. The design is better in terms of space utilisation, though I wonder how robust the sheet feeder will be - time will tell. Feeding of paper and printing is noisy and a little disconcerting as it sounds like things are going wrong, but they aren't. Being able to blow up A4 to A3 is another added benefit, once you've realised that you have to tell the printer you are using A3. All in all very pleased.
