Product conforms to the description, do not open rectangular boxes, according to the description, I have not tried to do it myself, easy to use and position (relative to electrical boxes works on feet) no need to hold the box, this is the object that is running, quieter than what I expected read the opinion, very effective at cutting level, it actually prevents injuries. Offered to my mother who is left-handed because she is fighting for years with boxes openers. And very easy to use.
