Product review (5 stars): Life saving, time saving, money saving!
This has got to be the best 23 bucks I've spent in a long time.  Our dryer had been taking forever to dry large loads.  90-120 mins on average.  It didn't used to take this long so I thought I would attempt to clean the vent and see if it helped any.  I didn't have high expectations but figured it would help a little.  I had never cleaned the vent before and I bought the house over four years ago.  I had never seen anyone clean one before so it never really occured to me that this is something I should be doing.  The kit came in two days thanks to Amazon prime.  Directions were very easy to follow.  There was also a DVD in the kit but I didn't look at that.  I didn't know how long my vent was so I just ordered the regular kit.  After starting the process I realized my vent was longer then the rods included.  However I worked from the outside then the inside and it worked out just fine.  I did about 80% of the cleaning without my husband.  I was a little leary since I'm not handy with repairs but decided to give it a try.  At one point during cleaning the vent was totally clogged.  Using the clog remover and the leaf blower (its in the directions) I got it unclogged.  Here is where the second person is handy.  If one person is inside cleaning and using blower then its nice to have a second person outside saying if the debris is still coming out etc.  I could not even imagine how much stuff came out.  The lint didn't really surprise me.  The twigs, wood chips, straw and feathers did!  Luckily I didn't find a bird or any other animals.  It was pretty scary removing the debris from end of vent outside not knowing what I might find.  How there was not a fire I still can't believe.  I had chills seeing how much came out of there.  The whole process took a couple hours because of the amount of debris and some learning on my part.  Hint leaf blower works better then shop vac.  I am so relieved I bought this kit.  Now the best part is I feel safer.  Also our drying time is down to 40 mins for a large load of sheets and towels!!!  This has cut the dryer time by more then half!!!!  I am excited for the energy and time savings.
