I don't have any experience with that trainer, but what you'll generally find is that mag trainers, versus fluid, have less of a "real" road feel, are noisier and not quite as smooth. If those factors don't bother you and/or you're not planning to use it all that often, then it might be a good trainer for you.
I went with a Cycleops fluid trainer after trying both both the fluid and mag. Granted, I can't stand riding the trainer anyway, but I will say that it at least has a decent feel and isn't very noisy.
Live with intention. Walk to the edge. Listen hard. Practice wellness. Play with abandon. Laugh. Choose with no regret. Continue to learn. Appreciate your friends. Do what you love. Live as if this is all there is.
