This review is ONLY addressing this sander from the prospective of using it and being left handed.  If you are left handed absolutely avoid this torture device.  First of all the "continuous on button"  hits you right in the middle of your trigger finger. To compound that,  it sticks way out and is particularly uncomfortable.  It is also possible to inadvertently lock the "continuous on"  feature unknowingly, making this tool potentially unsafe for a left handed person to use.  I sent it back immediately. I also called Porter Cable to complain about this lack of respect and concern for left handed people ........they couldn't care less about the 35 million  left handers in the US.......why?  By the way, this sander is overly heavy and quite noisy.  My front line sander is a Bosch 1274, really quite nice for left handers, but now unavailable.  Rats.!!!
