Product review (5 stars): Pleasant surprise.
We were not expecting much from this gadget but the low price did not make it much of a risk. We had tried using stockings to catch the lint that got by the dryer lint filter. It seemed the stocking soon plugged. Air presssure then built up inside the dryer forcing air out of the dryer around the drum seal, letting lint loose in the house.

This little thing seems to catch almost all the lint remaining in the exhaust. After 4 or 5 loads, it is simple to remove the top and replace the catch water. If it is a long time between loads, it is wise to check the water level and pour a little in through the louvers if needed. Though not meticulous, we like a dust/lint free home but dislike dusting. This little box helps accomodate both desires while keeping moisture/heat from the dryer inside the house.

Though a good value for its price, we would pay much more for a higher quality design of the same unit.
