Product review (2 stars): 2- It's supposed to cool off the the hot air that comes out of ...
No instruction in English. Shipment takes a while, it came from across the pond. But none of these are the problem actually. I finally decided to use it : 1-you need to fill out those 2 little containers with water and place them in the freezer long enough to freeze. 2- It's supposed to cool off the the hot air that comes out of the dryer. It doesn't work. Totally not worth it. It might work if there were 3 times the amount of ice,  and probably some water too , but not the way it is supposed to be used. I might try adding extra ice and a little water . But it doesn't do what it claims to do , which is cooling off the hot air. It does a little better at reducing the amount of dust/lint in the air than the other lint receptacles ( the ones you add water to ). All in all , not worth the $ 47.00 . Too much of a hassle to return, so I am keeping it, but I cannot recommend this product at all.
