Do not buy this opener.  Our old OXO opener finally gave out after twenty years of use.  This replacement is almost identical with handles that are redesigned a little.  At first we were very happy with the quality but a little frustrated with the opening process.  In fact it seemed to be already worn out.  We expected another twenty years of service, but no.  Regret to say that after 10 weeks of operation, opening perhaps 20 can, we find it worse than useless.  Hard to get it started, that initial clamping onto the can.  It seems to move the can sideways or causes the can to tip over.  You need to hold both the can and the opener then press down firmly.  Even then you may have to repeat this operation several times as the opener slips off the can easily.  We like the handles.  We like the black knob to turn the opener.  What we do not like is the very poor and frustrating process needed to open a can.  I have included pictures showing the components that grasp and move the cutter forward.  Notice the poor quality of the ratchet wheel and how dull the cutter appears.
