Product review (4 stars): Works as advertised
The product came with everything that is needed for a quick and easy installation.  During the late fall and winter months our dryer doesn't vent as well, so we prefer to use and inside lint catcher for two reasons.

Pluses
1) Release heat inside the house for free, versus pushing all the hot air outside.
2) The clothes dry at least twice as fast using this inside vent.

A couple down sides are
1) Should not use it in the summer.  It releases too much heat and humidity into the house.
2) The wall mount bracket they provide is not strong enough to hold the unit on the wall.  I just set mine on the floor and it works find.

Also, every couple weeks you need to remove the lint from the container and put some water back in.  But it's real easy to do and well work the quick dry times and "free" heat.

Remember, don't close the washer/dryer room door.  If you do, sooner than later, the heat and humidity trapped in a small room will start to peel the paint right off the walls.  If you leave the door open or even cracked a few inches, there's no problem at all.
