We love the product, look great. However directions were less than adequate. I hung the monorail and transformer and then one light. Before hanging the rest I tried it out only to have the transformer fuse blow. We tried everything only failing. Then the next day upon calling for technical help we were told we had to at least have two lights hanging in order to not trip the breaker. That should have been in the directions. We wasted a couple hours trying to figure out what we did wrong.
