This can opener works really well, has a nice sharp blade that easily punctures cans.  I really like that the blade unit comes off the can opener for easy cleaning.  You just push the button on the top of the unit and the blade unit slips off.  The handy hand held item for opening flip top cans is a bonus as well.  I don't have to get a butter knife out in order to open the flip tops cans, which there seem to be more of these days.  Good unit for the money!
