Shower booster pumps

[RogerM]

We have a shower on a gravity fed system that isn't quite powerful enough to provide an acceptable flow. Don't need a power shower, just a relatively modest increase in pressure. As an alternative to a full size shower pump, has anyone had experience of installing/using the Floflex SP2B In-Line Micro Pump? What's the verdict?
