There's a few reviews of Exus(=exustar) up on mountain bike reviews (www.mtbr.com) but none for that specific model. I like my Sidi bullets with the following caveat - very slippery. I'd hate to do much on rocky surfaces in these things. They use plastic rather than rubber grips and it shows. Otherwise, I like them a lot. The other shoes I've had (which Pyze now has) are Axo vipers. Not an easily available shoe, but lasted forever. The only downside with these is the plate is inaccessible from inside the shoe so you couldn't replace it if it stripped.
