Product review (5 stars): Took a little time, but my 12-year-old dryer is like new
I religiously clean out my dryer's lint trap between loads, but a few weeks ago my old Kenmore dryer suddenly decided to take a leisurely approach to clothes drying, taking almost 3 hours for one load. I took apart my machine and suctioned out every lint ball I could find with my vacuum, then cleaned out the hose and vent as far as my vacuum could reach, but it still refused to cooperate. I figured there had to be a blockage somewhere in the vent and decided to get the LintEater based on the reviews. And I'm so glad I did.

My vent is probably around 15-18 feet from dryer to the outside of my house, but I opted not to buy the extension kit because a) I was hoping that the blockage was within the LintEater's 12-foot reach, and b) I didn't want to spend the extra money if this thing didn't work.

On my first attempt, I attached the brush to one rod and secured it with electrical tape (I read other reviews about the rods breaking or disconnecting in the vent, so I made sure to take precautions). After snaking it through the vent, I pulled it back and couldn't believe how much lint came out - almost a pillowcase full. I added two more rods (secured with more electrical tape), went back in, and felt a little resistance. When I pulled back again, tons of lint and pieces of a birds nest fell out - thank god there were no birds or eggs inside. Still no air flow though. I wound up working the vent from both sides, with all four rods, then connected my dryer again, but still no air flow. So, with the dryer running, I went back outside and tried again. This time when I pulled all four rods out, I was blasted with an explosion of lint confetti. And even though I was cloaked in a dust cloud, I couldn't have been happier. My dryer is now back to its 30-45 minute drying speed.

TIPS:
- Electrical tape works wonders in ensuring that things don't detach inside your vent
- Don't attach more than two rods together BEFORE snaking them into the vent - attach additional rods to ones that are already in the vent
- If you have a longer vent but are on the fence about the extenders, try working the LintEater through both sides of your vent - it might take a little longer, but it worked for me
- If you have a cordless drill with a lower torque rating (like mine), your drill may struggle a bit when cleaning with four rods attached, ultimately leading to the battery draining and you having to pick up where you left off the next day (like me - it's all good though!)
