Disappointed after a short time

Have the duvet now since the beginning of December in use and had to go to the initial euphoria, unfortunately, very quickly get to know the disadvantages. Spontaneously a cuddly soft blanket and absolutely suitable in use as a double blanket for the winter. But after a few weeks, the lumpy duvet and the snaps with which can be connected the two ceilings, dissolve at the slightest movement (have unfortunately a very restless sleep). I would in any case not pull my bed every day, to "adjust" this new.
Too bad had to have been looking forward finally found me soooo great a duvet with good value for money.
At least 3 stars, for the really very reasonable price, but in the future I give rather from a little more, and then hopefully get the desired quality.
