Not too flexible.  You'll need to tape the sections and glue the head.
This set is Made in China and does not have specific brand labeling.  So it could be sold as any brand.  For that reason, you’ll want to look around to see who is offering the best price.  I find the current price of twenty-four bucks to be quite expensive for plastic rods and brushes Made in China.<br /><br />The instructions show that you will probably want to use duct tape to secure each section together after you screw them together.  This  is certain true, as sections could unscrew as your working the brush back-and-forth. . . especially if using a drill.<br /><br />You may also wish to use super glue (or some other glue) to attach the brush head so that it does come unscrewed.<br /><br />The rods are not that flexible.  The more rods you attach, then the more curved it can become. . . but. . if you that some “tight turns”, then this may not work.<br /><br />This set comes with two brushes.  The bristles are a good combination of flexible / stiff.  The  brush is 4-inches across, and about 1.75” wide.  The brushes must be used separately, and can to be attached together.<br /><br />I wish that someone would invent a dryer vent cleaner where you could attach some kind of hose to a vacuum cleaner.  Because once you use such a brush. . .  you’re going to have to get the lint out.  If you have such a hose, then you could possible attach it to this brush / pole set.
