Product review (5 stars): THIS PRODUCT GAVE ME ASTHMA
Why am I scream typing? Well, because this dang product gave me asthma.
Were clean people. We clean the lint trap on the dryer religiously. There cant be that much crap in the vent, right?
 FREAKING WRONG 
It all started simply enough. I read some reviews, got the cleaning kit, read the directions, and went to town. Started by cleaning inside first, sending the brush down the duct to the outside of our house. Even got the blower and put him to work [thanks to a tip from another reviewer]. Meh, some junk came out, but I wasn't expecting a ton, so I moved outside.
Ew. All the junk came out. Ok, this thing works. Ran it through the duct a couple more times... oh hey, grab the blower and jam the nozzle up the duct too, for good measure. Cool, Im done. Let me go back inside and reconnect everything. 
You know when you burn something in the oven and that faint amount of smoke creates a haze in your kitchen? Ha. Thats what I was greeted with when I came back inside. Except I didn't have anything in the oven... and Im perfect, so I never burn anything.
Walked in to the laundry room and the haze is now a thick fog. I live in the south, so humidity isn't anything new, but this was late evening, and we hadnt had rain in about 6 hours (which must set some record, as weve recently negotiated a break in the rain hostage weve been in for the past 2 weeks). What in the fresh hll is going on?
I move to the back of the dryer and there are mounds of lint just waiting to exact their revenge. The coughing starts. My contacts are all of a sudden plastered to my eyeballs, and Im considering my options on emergency help since my husband is out of town and the dog doesnt know CPR.
Do you see the broom in my pictures? Hes dead, laying on the floor. He straight up said, eff this, Im out. The attachment for my sweeper vac is holding on for dear life. Theres dust EVERYWHERE. I saw a mouse packing his belongings and move his mouse family out of the peephole in the baseboard.
Im still coughing as I write this. And I have a couple lessons to share:
1) if you think you're clean, maybe you are, but this Deflecto kit will check your ego real fast.
2) maybe place a bucket or something over your inside duct if you're going to use a blower for additional assistance on the outside vent. Perhaps this may have prevented dust and dirt from flying everywhere.
3) ... or maybe don't use a blower? This kit does a pretty good job on its own. Or use a blower. Whatever. Get asthma while trying to do chores. Have a nice life.

This product works. Five stars. Well made. Good value for the price. Easy to use. And all that jazz.
