Purchased the same dryer about 2 weeks ago. Have noticed that drying similar items works perfectly. However, drying thick and thin items together leaves some of the thicker items damp. Try shaking out your items before spreading them loosely in the dryer. You can also add a few minutes to the drying time but in the preset mode when the sensor senses that the items are dry the dryer will shut off regardless of the time remaining. All of these suggestions worked for me. Very happy with this purchase.
