Product review (3 stars): Useful if you don't have a line to run outside ...
Interesting product. Useful if you don't have a line to run outside but want to trap some of the extra lint. It's hard to tell if it works because the lint dissolves in the water at the bottom. Also, the product obviously doesn't address the added humidity that comes from not having an exhaust vent. Better than leading your line into a bucket or other alternatives.
