After using this twice to pump a total of 24 gallons of fuel the screen does not work. Replaced batteries and still the screen is unreadable. Not even in service for 2 months.

Bought this last year (2024) and it has been working fine so far....

This seemed like a well made device, but I didn't end up using it in my application.

Previously purchased same meter by different manufacturer from Amazon,but had to send it back because instructions didn't say how to change from liters to gallons. This one has understandable instructions. Very difficult to seal poorly machined or out of round threads on this meter. Took three tries. Used high dollar pipe sealant, Water Weld and lots of torque on the third try. Dry fittings now.

So far so good. Bought these to measure Mosquito Control chemicals. Once we got it calibrated, everything‘s been working great so far.
