Most Popular 7-1/4 Inch Extension for 2018 Subaru Impreza

I can't believe how much this thing wobbles inside of my hitch, and how much my accessory wobbles inside of it. Two wobbles don't cancel it and I get wobble-wobble. I have yet to use my accessory because that just won't work out. I'm trying to use the Rhino T-Loader so that I can load a kayak on my roof. Paint also chipped off so easily from playing around with installation; I didn't even USE the accessory yet. For the cost of this chunk of metal, I'd have hoped for better fitment. Most anti-rattle devices only work for securing the accessory-to-hitch end. I'm not quite sure if I can stabilize both ends...

Product was delivered on-time as expected. This adapter is being used on a Volvo XC60 with a retractable receiver. Although it fit in the receiver the locking hitch pin did go all the way thru without a little brute force. Not sure if it is a receiver, adapter, or a hitch pin problem. Would have been nice to have a little more guidance.
