Product review (5 stars): Like others, I didn't even look at printed instructions ...
Kit came in 24 hours; parts all jumbled up and not padded, but nothing broken and all parts accounted for.  Even comes with a Phillips screwdriver adapter for the included stainless steel torx screws.  Like others, I didn't even look at printed instructions but followed YouTube video on installation; took about 10 minutes.  All parts fit properly and work well.  I can't believe all the hassles I've been through in the past few years trying to jury-rig some kind of "fix" that usually only lasted a few months at a time!  The metal bracket rails and wheel axles look a lot sturdier than the OEM ones.  Wonder how long this product will be around?  Maybe I should get another one now!
