Unfortunately Descaling is quite a mess. It lasts not 35 Minutes, but rather over 1 hour - at least felt. Here, unfortunately, the engine is running and the internal water drain in the base (bottom drawer!) Full, the then little can be "no accidents" emptied. This process also works in normal operation full of water and has to be emptied regularly - as already mentioned other Rezis really unnecessary and difficult to operate.
Otherwise fine and solid.
