have not seen yet.; however, think your customer service rules Suck; I am now out $350 from you and my latest is a broken pub vhair, used 3X, but is out of warranty so am out the repair of that.  Do not bother to charge me for the above as you have really taken enough advantage of me already and I have learned - the hard way - not to ever be a customer of any of your companies again.  If you cannot stand behind your products, you should get out of business.
