Product review (5 stars): Handy and durable lint trap
This is the second LTF Lint Trap that I have owned.  I purchased the other one several years ago because I could not gain access to an outside wall from the dryer.  I purchased this one from Amazon.  This device is easy to install and does a good job of catching the lint from the dryer.  I merely inserted two screws into the wall just above the dryer and placed the lip of the device on the screws.  The device has serrated edges on each end of the lip so that it does not wander.  It is important, however, to frequently check the water level and to keep the unit clean.  Otherwise, lint may dry and build up inside.  Failure to do so can result in the lint becoming somewhat caked on the inner surface.  It is not impossible to remove, but the effort is significantly greater.  The reason I purchased a new one is because I am selling my house and a new one just looks nicer.  Also, the hose supplied in the box may not be long enough, depending upon where the unit is placed.  I placed mine on the wall just above the dryer, and I had to purchase a longer vent hose. Be generous when determining the length of hose so that the lid is easy to remove and put back in place.
