When I first got this machine, I wanted to send it back, it took ages to heat up (I actually thought it was faulty). The time to dry everything was dramatically extended (If I washed a top on a quick washing cycle, I could dry it within 15 mins in my old dryer - no chance in this one) however, if you are happy to wait, you can put a mixture of items together (jeans, towels, cottons) and they all come out perfectly dry, no shrinkage, no tangling up etc. So, it’s all to do with speed really (everything will take a couple of hours), but the cost of drying is reduced, apparently.
