This trainer isn't currently working, but can be repaired by someone with the time and know how.
I believe the problem is the speed sensor, but it may be another issue.
Here's a reddit discussion about a similar situation.

Get a nice trainer for a great price if you're handy. I don't have the time to dedicate.
