I liked that it reads in US and metric units and can be calibrated for accuracy. But the impeller was not stable and quickly blocked, and the LCD leaked water despite the rubber seal. I suspect that for a fluid with lubricating properties like diesel (not the coal tar coating I used it on) this might work well to keep the impeller clear. Revain made it easy to return with Prime.
