Review title is Don't believe the hype [SEP] This nozzle is called &#34;unbreakable&#34; but it's very breakable.  And it doesn't stay on my Solia hairdryer.  I even had my fiancé use a professional drill to put this thing on and still it kept falling off.  After the first one broke, I thought maybe it was a fluke (it broke for good after my sister used it on my nieces very thick/coarse hair)  so I ordered another one.  The other one doesn't work any better than the first one.  I'm very disappointed in this very expensive but ineffective product.
