I bought one (different "brand" and colour, but looks exactly the same as your pic). I sold it on to a neighbour recently, and AFAIK, it's working fine (total of roughly 3 years old now). Only reason for selling was me slowly but surely packing up complete workshop/moving to a flat.
Mine was fairly noisy (universal brushed motor) but worked pretty well/did the job, and the DE was not too bad (AND the dust outlet was a straightforward fit direct on to the nozzle of my shop vac - now there's a rarity)! Despite what I anticipated, changing from belt to bobbin and vice versa was simple and quick.
Mine cost roughly 150 quid equivalent and I'd have no problem recommending it.
Very useful for all sorts of sanding & light shaping jobs (I also have a combi disc/belt sander) but (crossed with Spectric's post), agree that it's NOT a "precision" sander - but you can angle the table down to max 45 deg for champfers, etc (if I remember correctly).
