I used zagster when my husband was still working as an engineer for BMW i3 project at MKE (Milwaukee). My husband loved it so much that he decided to quit his job there just because of the great experience he had while using this service. The only thing we dislike about zaggster is its price which can be expensive especially if you don't use all services offered under one account. We have been using zagster since last year and haven't encountered anything bad or even good enough to mention. It's totally worth trying out. I highly recommend using zagster. They helped me with transportation needs during work hours.
