I bought one back in 2006 because I was going to be doing a team desert race on my friend's bike which had one installed. I liked it so much that I left it installed on the bike. I really liked it because it taught me how I was supposed to be using a manual clutch in racing and difficult technical trail environments. It taught me that you don't always want the engine coupled tightly to the transmission, especially in very tight slow trails. It also taught me how to smoothly clutch through a corner in order to get the best corner exit speed.
Basically, it taught me how to be a better rider.
I have several bikes and only one has a Rekluse on it and I can tell you that I never had any problems transitioning from the auto clutch bike to a manual clutch bike.
However, I will back up what Jon Andersson says about an auto clutch on tarmac. I always rode a gear lower to put the engine in a higher rpm range on tarmac because it seemed that the clutch was slipping quite a bit in the taller gear. I had the Z-start in my 501 with tungsten balls in every slot to get it to lock up at lower rpm but I also had a stiffer spring installed for quicker clutch engagement for launching up rocks or over trees. It took a lot of trial and error to get the adjustments dialed in just where I wanted it, too. I think that bigger engines with more torque don't respond well to the Z start (I have no experience with any of the newer designs from Rekluse) and I would hesitate to install one in a 600. Matter of fact, Rekluse themselves didn't recommend an auto clutch for a 650. I think it worked well in my 501 but was tops in my old 2005 KTM 450SX race bike which was very high-strung.
