A year later & a 1-2 foot wake so now its 2 stars.  Bent and released 1 mooring (I was using only 1 of these for the back) for my jet ski in what was a pretty good wake.  The plastic gave at the thinnest point that you can see in the bottom left of the picture.  So these are maybe still good for a quick dock connection if you moor/attach at two points and stick around but I wouldn't trust them for a great deal more.
