This excellent, efficient steamer is a definite improvement on the previous model, in that it is easier and safer to refill without disturbing the steaming process. Also, layers can be used individually, so you don't have to worry so much about getting the right thing in the right container before you start - ideal for a muddle headed cook like me! In fact, the only complaint I have is that there are no handles on the condensation tray, so it can't be emptied. But that isn't the problem I first thought it was, because it overflows back into the water reservoir. I'm not sure I like that though, the idea of having condensation fall through the food, picking up colour, flavour and debris, then overflow back into the reservoir doesn't seem quite right to me, but it doesn't seem to get too dirty. And this does only happen on a really long steam - like the Christmas puddings, which are all wrapped up anyway!
Another plus is the size of the reservoir - this model holds enough water to allow cooking through the entire time on the dial. So no boiling dry with this one - which is what killed my last one!
One of the best aspects of the previous model is still present - the compact nature of the storage. It all fits into itself and packs neatly into a small space. This one has an even smaller footprint while cooking just as much food. In fact I managed to get an extra pudding basin in this year!
