Cleaned my vent like magic. Then comes this gizmo on the amazon deal of the day. Save me a lot of time and keeps my vent clear.

The hose is small so if there’s a big clump it gets clogged, remove the clog and continue. No more lint inside the lint trap or the dryer. It helps to get the end of the hose into the nooks and crannies.

The tool has a natural bend in it which makes it easy to fold in half. Easy to read instructions. Much easier than cutting my hand on the sharp metal edges under the dryer.

The tube is so tiny that it clogs the second it gets near lint. A thin wire wraps around the tube to keep it sort of stiff, but it's very hard to control. The wirre is not very flexible at all, so if you have any tight curves in your vent.
