I am looking to buy a trainer for my husband but I don't know much about the trainers. He is a recreational biker and often gets home too late to go for a ride outdoors. I know that he will like CycleOps virtual training so that is why I am going with this brand. What are the advantages/disadvantages to electric and fluid.

Thank You!

I apologize if this is a repeat question. I searched the thread but didn't find anything on this topic.
