I've never had a perfect can opener before.  I decided to go on the high end this time and am glad I did.  It hasn't threatened to tip over yet even when loaded with the 28 oz tomato can.  It also doesn't spatter everywhere at the completion of rotation. ( I hate that!)  The can fits into the cutting mechanism first time every time.   I've had it less than 6 months but am totally happy and hope this one will last forever!
