The nut that accepts the threaded bolt (which connects the bike carrier to the hitch rack) is welded and the welding is defective. One trip is all it took for the nut to come loose and so, it is broken. Cannot tighten the bolt anymore. Luckily the pin stayed, otherwise it could have caused a major accident because the bike carrier could have come loose with the bikes and hit any cars behind us. So, watch out. This is not acceptable at all. Now, I have to manually saw the bolt out and somehow remove the rack to return. What a pain!
Beware, Weak welding of the nut in the tube that connects to hitch rack

I had a lot of faith in this product but when it arrived I was unfortunately, let down. The sides of the frame are much wider than expected and the sound quality isn't true bone conduction. It's honestly just very small speakers that when turned up at full volume, everyone around you can hear what you're playing. Additionally, for the price, they could at least come with a case and not a folded cloth.
Great idea but not worth the price and not true bone conduction.
