Product review (5 stars): Good range cord, standard nema 14-50p fits with nema 14-50r
This product is a pretty simple one.  I do like prettymuch any product made by Southwire, they make good stuff. Coleman cable is now a subsidiary of Southwire.  If you go to your big box stores, most of the Romex you'll buy is made by Southwire, same with THHN / THWN you'd buy for conduit.
I like to stick with brands I trust to make good products.

I have no particular complaints about this, fits well in Leviton 14-50r as expected.  Well constructed and sturdy.  I like the 6-foot model so it's easier to install and pull out my range if needed.  Installation is simple with the prongs crimped on.
