Total Waste of Money
I'm really not understanding the good reviews on this product, it just doesn't make sense to me.  This thing has no power at all - it might be different if it was variable power and this was the &#34;low&#34; setting, but it just bogs down completely the minute it touches your nail or tough skin.  The attachments really are lame too - they each are supposed to have a different purpose, but each one performs about the same.  It is battery operated or AC plug in.  The battery power you might as well forget, but the plug in (which I used) - again just not enough power.  It does come with batteries.  Switching out the attachment heads is very easy, they just push in and pull out.  One drawback to the electrical plug in option is that the cord on the main unit is coiled and quite short.  When I plugged it in to the extension cord next to my bed, I had to put the plug in part up on the bed to have enough leeway to use the unit.  Very stiff coil.<br /><br />It has a few attachments for acriylic nails - which I wouldn't use - anyway, not worth the money in any way.
