These work great for my boat trailer.  Dang near began sailing down the driveway when I was working inside of it on the trailer. Decided I need to get wheel chocks... a 2x4 wasn't cutting it. As far as packaging is concerned, the frustration free packaging is just a ploy to get more money for packaging.  Just get them as an add on item with another purchase.  The packaging I got was in no way frustrating, just in a basic box.
