Familiarity: I've put it through the wringer
I ordered this with the idea it would be sued for 3 mountain bikes. So I'm probably pushing the limitations of this item. I found that the 1 1/14 fitting doesn't fit great on a 1 1/4 hitch. There is some wiggle that found nerve-wracking. Others online posted similiar observations, so they filled the gap with quarters or cardboard. Helps in immediate short-term, but just not a great fit overall.
Additionally, the pieces that you assemble don't come with torque requirements and are largely made up of plastic parts. With some slightly heavier bikes, these moved these pieces around a lot so I could watch through my rear window as the bikes slowly shifted over a drive. I only had this product for a month and I noticed all of these changes.
If you're using this for kids bikes and road bikes and occasional 1-2 mountain bikes, this is probably fine. If you're going to be using this for 3 mountain bikes, look to something beefier, like 1up.
