DIGITEN Water Flow Control LCD Display+G1 Flow Sensor Meter

This unit that I purchased works okay, however there are some limitations. For one thing as soon as it comes on it doesn't start tracking flow. You have to push the Run button twice. Also a very nice backlight comes up when you turn it on. But that's the last you'll see of it. Because it has a timer and turns itself off after about a minute. It's hard to see the screen and the details listed unless you're perpendicular to the screen and looking right at it. The backlight helps with this immensely but you cannot turn on the backlight or leave the backlight on while it's running. Also it runs the program such that it totalizes the amount of water flowing whether you want to do that or not. And it also has a shut off limit on total flow. And, it can only pass so much water before the program ends. So functionally, it does do what they claim it does and it does it pretty well. But there's a lot of other limiting factors that take away from its overall performance.
