Just received this in the mail today. I know a hand full of people have used the seasucker brand. I was going to drop the 300 on that until I stumbled upon this rack. I usually avoid the cheaper alternative but after reading the reviews I thought I give it a shot!
First impressions were good, I mounted up and took a light test drive. Works exactly as advertised. Just be aware that it only comes with adapters for 5mm axels. I have to order the 10mm ones before I’d actually take this out on any long drive or the highway.
