I give it a 5 as I read other reviews prior to purchasing so knew what to expect with a non vented heat pump dryer. In that it takes longer to dry and items are not always that dry. I find it's the larger items like sheets which don't dry well, even when it's full of clothing after 2 1/2 hours they appear to be dry.
The biggest issue I had is that I needed an integrated / built in machine and I had the old vented Baumatic previously. This one is the same size etc so things are more straight forward. But they've changed the legs - not as sturdy as the previous legs, one snapped! Nowhere to screw the machine to the side of the units so as the door is really stiff the machine rocks when you open and shut as it's so light so I had to put battens on so it doesn't move forward. The instructions for the door fittings describe the fixtures but there is no inventory so you can actually locate each fixture. The screws for the door hinge are really poorly designed - TIP screw them (use a spanner) into the machine first to make the holes then unscrew and screw in place with the door and fixtures else you'll never get the door tight.
