Night and day over a regular mach shaver.
Huge improvement over a regular mach shaver.  I use the regular mach blades instead of the newer more expensive ones and get a close comfortable shave every time.  The older blades seem to last longer and the battery never seems to run out on this.<br /><br />Update-August 2009 - 3 STARS for the handle.  5 STARS for the BLADES. I still really like the shave I get with these blades and the power handle.  My problem is the quality of the handle has gone way down.  My first one lasted forever.  I left it at a hotel and figured I'd just buy a new one.  The two replacements I've gotten both stopped vibrating within months.  The first just stopped.  The second seemed to have some leakage.  I'll try one more since I don't want to get sucked into the fusion hype and expense.
Rating: 5 stars
