One piece was bent so poorly that only one bolt ...

One piece was bent so poorly that only one bolt could be secured. Not stable enough to use. I threw it in the trash.

One of the running boards arrived with a good size dent.  I got over it and started the install.  Normally it would be a very simple install.  This set was not.  The nuts that welded on the bracket for the non-threaded frame were welded crooked therefore the bolts would not thread into the nuts. Overall product looks good on the truck but be careful and check the product over before installing.

Super cheaply made one of them broke on install, short metal stud didn't work for my front application as planned

One of the bolts is filled with metal. I need a replacement bolt. Called the manufacturer and they were very nasty and said the seller of this item is "only a seller of our product"

Decent piece.  Not the quality level I was expecting - one piece cracked during assembly.

Studs broke on one spacer.  Almost lost a wheel on the freeway, pulled over on time, only one stud/lug nut was still there holding the wheel on.

Package arrived in one piece but it was severely bent. Thankfully it was fine for what we wanted it for but if you are purchasing for a collector I'd think twice.

Unfortunately the bolt slots were too small. My foot board bolts are 5/16". The slots appear to be 1/4". Also, one of the brackets was bent which I can't imagine passed any type of quality assurance check. The metal is thick so it had to be a manufacturing issue which is why the low rating. Otherwise it looked good and would've worked.

With both pieces tightened all the way, the right one held great while the left one had some movement. I used the shims provided but just wasn't quite enough. Once I had figured this out I had already installed the set and scratched the bolts so I wouldn't imagine they would accept a return - therefore I live with it. If both attached perfectly I would have given it 5 stars.

One of the bottom corners was bent upwards nearly half an inch... managed to even it out a little but indicates poor quality control

Nice, but only 1 of the 2 pieces was threaded to attach to my Nikon FM. So only one piece was usable.

They are small and heavy and packaging was poor as one piece arrived broken.

Shoddy workmanship, but expected that from the low price. Two of the holes in one of the support arms were misaligned. Took it to the drill press to re-drill, which allows the bolts to go through both sides now, but now have a figure 8 shaped hole. Reinforced with a couple of washers. The two holes that mount the upper assembly to the 2 hitch bar are also misaligned resulting in the carrier portion being off angle from the vehicle. The result is that the drivers side sits closer to the vehicle bumper than the passenger side. I only need this to get our bikes to the local park, so it doesn't have to look good.

It arrived with the nuts and bolts falling out of the box.  The shelves were bent and some look used.  No instructions in the box.  I was able to put it together after buying more screws.  4 hours to put together.  I'm glad I only ordered one.  I needed 5

Only one piece was in the order.  I am frustrated.  The Q&A section as well as those photo let me to believe there were 2 pieces.

One of the pieces was damaged or something. It only worked fine about 1 day :(

One leg of hitch slightly twisted causing last attachment bolt to be badly misaligned with threaded hole in car frame.
