LintEater Kit works PERFECTLY! Not a lot needs to be said about this product. It does exactly what it was designed to do. This is just an extension for the original LintEater Dryer Vent Cleaning System.We have an unusually long dryer vent that carries the dryer exhaust from the ground floor of our house out the roof. A couple of bends in the route also make it tougher for the lint to make it outside, so it just clogs the vent pipe. We noticed the problem when our dryer started having problems getting the clothes actually…well…dry. After doing quite a bit of online research, we figured out that it was likely not anything wrong with the dryer itself, but just a clogged vent system.We gave a cheap little hand-held brush a try, but it didn’t do much good other than cleaning out the dryer itself. I found the LintEater system and read several favorable reviews, so we ordered the kit. Man, it sure worked like a champ. Pulled an amazing amount of link out of our vent pipe. The only other problem we had is that we neglected to order the additional extensions, so the cleaning system only went about half-way through our pipe. The drying improved for just a bit, and then almost stopped completely because the remaining lint had been compacted into a mid-way point of the vent pipe. We quickly ordered the extension kit and once we used it, the dryer is back to drying beautifully.The LintEater system is very easy to use if you have a power drill (cordless or otherwise). We use a variable-speed drill for ours so we can vary the speed as the brush snakes through the pipe. It can bind-up in tight corners a bit, but if you just work it around some, it will pull right through and does a great job.I highly recommend this kit to anyone who is needing to clean their own dryer vent.
