Query: A complete waste of money

The small diameter, coupled with the length and deep-ridged construction causes this hose to produce so much friction that there is no vacuum to speak of and therefore NO DUST COLLECTION. I first connected this to my 2hp cyclonic dust collector. There was barely any air movement at the 1" end of th hose. I then used my 6.5hp shop vac with similar results. I went back to duct-taping a 2" hose to the underside of my bosch sander handle which works fine, except that the hose is a little unwieldy. Better unwieldy that dust all over my shop and the work. DONT WASTE YOUR MONEY ON THIS PRODUCT!!!!
