Got an ez-slalom course kit from Ed Obermeier. The buying process was very good, and Ed was extremely helpful and informative. Instructions to build the pvc arms were clear and not difficult with the right tools (band saw and pedestal drill). Everything else but the anchors was included and of excellent quality and workmanskip.
Installation was easy, except for a moment where we were interrupted by two persons on kayaks that asked what we were doing and other stuff. We got tangled but were able to resolve it without damage. Lesson learned: when installing a portable course, if someone approaches, it is better to be unfriendly...
Bottom line, very happy with it.
