I am so pleased with this item.  I was expecting it on Tuesday but it arrived on Saturday!!  I had just been out in the rain (running in the morning) and by day my boots were pretty damp.  I didn't even look at the directions because the machine is so well thought out and easy to assemble (just popped on the extensions in about 10 seconds)  The blower is on a timer for both heat or just air. My running shoes (which were pretty wet) dried in an hour with the heat.  The boots didn't even need the heat.  The blower itself is very quiet....I guess I had anticipated the sound of a "blow dryer" but not the case with this.  I recommend this item to any and all athletes because it so effectively dries out your shoes.  This is a wonderful item and a great gift.  Jon
