I did not run mine for a long time. T rex makes them, as I recall. Maybe 1000 miles? I ended up selling it to my friend Jay (Manricing). He used it for a while. Hes no longer with us, so I dont know how durable it was, long term. It has those heim joints in each end, so there is some type of bearing, just not like stock. They looked a LOT like Toyota car steering link joints.....As far as feel, I really dont have that much experience with just it, by itself. I had a stock shock revalved so it was only on my "stock" bike for about 3 weeks, but the suspension action felt good. Nothing was binding.
I liked it because it was a cheap way to experiment. Once I ride with it, I knew I liked the added height and made sure the shock I bought had this feature. There was a sweet spot where the bike just felt right.
