Nutone mainly sells "Contract Grade" products and that is exactly what this crevice tool is. The tool has a satisfactory thickness for domestic use, even with a central vacuum (as in my case). However, its construction is unreliable, so it cannot withstand serious abuse or commercial use. I suspect this one-piece molded plastic piece costs about $1 to make and sells for about $14. What makes up for this is that shipping is 'free' (at least with Prime) so I hit the 'buy it' button for convenient home delivery.
