Don't Buy It!!
This attachment worked great for about 15 minutes before it suddenly stopped working.  It seems that I have received a defective unit.  For the price I paid and the amount of time I waited for it to arrive I can say that I am thoroughly disappointed and unhappy with the product that I have received.  I warn other shoppers to beware that you may receive a defective unit that will seriously disappoint you.  Looks like I will have to go back to the batteries now.
