Bought this to replace our old vented dryer. Looking at our smart meter, it seems be using around 5-9p/hr compared to around 90p/hr for our old vented one, so very happy with that.
Dries clothes well, and relatively quietly. Also dries bedding and towels well. Cycles take longer than our old vented dryer, but that's to be expected.
Read other reviews about it not spinning in opposite directions. When using the bedding setting I found it spins clockwise for a long period of time and then anticlockwise for about 10 seconds, then back to clockwise. When washing lots of bedding (1 double sheet, 2 singles and 8 pillowcases, and then a second load of 1 double duvet cover and 2 singles) it does roll into a bit of a ball but they still come out dry, so no issues for us.
Overall very happy with it, although the heat pump ones are still pretty expensive.
