Okay to get tough guide for flow rate at taps.
Only used as one off measure flow at a couple of taps in the house. I can't really testify to the accuracy, as I haven't validated the readings. But as it goes, seems to be okay to give a rough guide. It's plastic, so not the most robust cup I've seen. There are cheaper ways of achieving the readings, but it is easy to use.
