Product review (1 stars): Garbage
This thing is not functional in my opinion.  I bought it instead of running a proper vent and knocking out glass blocks in the basement exterior wall.  That was a mistake.  This thing supposedly catches lint in the water which might work if it didn't dry out the water after ~5 loads of laundry.  Even with water in it, the base unit is flimsy and is easily knocked over.  The top doesn't fit correctly.  Lastly the plastic clamps that they provide with the unit are complete garbage.  You will need to purchase a steel hose clamp that you can tighten with a screw.  For my situation this things fails in many areas.  I do not recommend it.  Spring for the extra money and install a proper exhaust if possible.

Do this instead if you MUST have something like this and cannot install a proper vent.  Get a 5 gallon bucket with a lid.  Pool supply companies sell ones with chlorine tablets in them and they are sturdy with a screw on lid.  Buy vent hose.  Find a metal tube that the dryer hose can fit over about 6" long.  Use tin snips and cut 6 slits 3" long.  Bend the slits out so now the tube is 3" tall.  Cut a hole in the center of the bucket lid.  Insert this metal thing through the hole and seal it with Gorilla Glue.  Trust me on the glue.  Then drill a BUNCH of 1/2" holes around the lid edge.  15 should do.  Fill the bucket 3/4 full of water, screw on the lid, attach the vent hose at both ends and you now have one that actually works for more than 2 days.
