Overall sentiment: negative
Customer reviews:
Power cord cap is hard to secure on to cable, doesn't fit very well on to plug to protect it.  Today went to plug in heater and the little plastic strap broke.  Now I have no way to secure cap to cable:( 
 when I received this cord cap I wanted to install on my block heater. This thing is probably the worst cap I have ever seen. Being an electrician for 34 years I know what I am talking about. DO NOT WASTE YOUR MONEY!!!  I would rate this a negative 10 if I could. What a rip off. Cap will not stay on any male cord cap I tried and I tried 10 different brands. If you need a cord cap keep looking. 
 Really cheap and flimsy not worth the money. I still installed it. 
 Thick rubber, but too small for plug. Had to cut side so plug would go in. 
 Don't get how to put it on 
 Really weak product, super cheaply made, very thin fragile plastic, it's not going to last more than a month 
 Won't fit an F-250 and if it did it wouldn't last a year. Very thin plastic. 
 The lanyard broke before I had a chance to use it, and  it's hard to get over the plug. Doesn't go over the plug very far either. 
 It's too tight on the plug doesn't fit all the way on. 
 Had end rip off shortly after installing 
 no comment 
 It had to be forced on. Not very good. 
 This doesn't fit anything. It creates a vacuum. 
 It doesn't fit the end of a standard cord. You can kind of work it on, but it's not great. 
 Don't waste your time ordering this if you purchased a Kat's cord for your Ecodiesel - the cap doesn't fit to male plug on the end. Might as well go buy a cheap lamp from Walmart and use the prong protectors for a cap. 
 Don't waste good time on this. Doesn't work. 
 Had a hard time using it on an extension cord as it was not built for them. Probable good with small cords instead the extension or heavy duty cords. 
 Too small to fit on the plug easily. 
 I have a Katz block heater on my truck and this cap is almost useless.  There is no way to attach this cap nicely without physically cutting the cord, putting the loop over the cord and then fixing the cord.  I ended up tie-wrapping the thing to the cord and it just looks bad.  Second, the cap is so hard to get over the cord end.  You have to force and contort the thing to fit and when it goes on it just doesn't fit right, it's all pushed out from the sides.  When it's below zero out it's even harder to get the cover on because the plastic is so cold.  What they need to do it make the loop that attaches to the cord more flexible so it can fit over the cord end and then it can retract and change the cap to something that the plug end would plug into and not try and cover the whole thing.
