Title: Worst purchase I ever made
Review: I bought a Dolphin Diagnostic from the official maker or distributor.It does not work in a fiberglass pool: can't climb on the ledges and it gets itself trapped into one end of the pool, just moving back and forth on almost exactly the same path for hours.The tech support guy was more interested in making a sale than helping with anything. After I described him the problem he suggested that I buy a different set of brushes, designed specifically for the fiberglass pools - very expensive PLUS an outrageous shipping charge. It turned out that the brushes it came with were actually the ones best suited for the fiberglass pools (but they didn't work) and what he made me buy were brushes designed for concrete pools.Avoid buying it.
