Product review (5 stars): Heavy Duty and Works Great!
I purchased the 10 foot version of this cord and it is very nice and heavy duty.  The wire inside is 10 gauge stranded wire, which was perfect for what I needed.  I am using the cord to power a home brewing kettle, so I was able to cut a bit off the end and use the 10 gauge wire from inside to wire the internal components of the kettle, then used the remainder for the actual kettle plug to my dryer outlet.  It works perfectly and delivers consistent power to the water heater element in the kettle.  This cord was significantly cheaper than anything I could find locally and yet appears to be better quality than the shorter cords sold in the stores near me.  I have no complaints at all.
