Loved our 1-hour tour with Eridani. Never been on a segway before but Eridani's instructions and safety briefing had us up and going with confidence in a very short time.
It was a fun tour as well as informative. Even though we are Aucklanders who have been to Devonport heaps of times, Eridani showed us places we'd never been to.
Eridani took great care to ensure we were safe at all times on the Segways - checking traffic, alerting us to bumps in the footpath or pointing out low-hanging trees in our path.
My only criticism is that they didn't respond to my phone message or the paid online booking. I had to phone twice to get hold of them and ensure they'd got our booking (which was for a special date that I didn't want to miss). However, I suspect that most of their customers just arrive at Devonport Wharf and phone them from there.
