Not for me

To be honest, I haven't quite tested the functionality / accuracy of the flow meter, rather, first thing I did is measure the mA consumption and that threw me off completely. At ~4.15mA that's just way too much for what could be considered a "sensor", sure you can make a sensor that uses any level of power and it would still be a sensor, but that doesn't mean that its very useful because these sensors are mostly used in battery applications and at 4.15mA that's about 20 days worth of use (~481hrs) with an AA battery of say 2000mAh. If you're running your project with a PSU, then this unit might be ok.However, another point worth noting is that the internal magnet which is essential for getting the pulse readings doesn't appear to be protected by anything, plastic / epoxy, nothing, so that means that it will rust. I looked at it under a microscope and there was nothing covering it. Indeed it could be some alloy mix that has anti-rust properties, but I doubt the chinese will use a quality magnet in something like this.

Flows <1LPM

This item claims to be able to flow 6L/minute. I couldn't get more than about 1L/minute through it. I looked into the inlet port, and there's a flow restrictor molded into the port. I measured it's diameter at about 1.3mm. A 1.3mm orifice would flow only 2LPM even with a 200PSI pressure drop, far more than this unit is rated for.

That you have to use a hard plastic tubing like Pex

That 3/8 " is the od of the tubing used not the ID

degrades

after about a week of use its will let water pass and not count. was good at first but after a week reading are way off.

Works on 3.3V logic

Working as described. Also good to know for some: I'm using this on 3.3V logic and it works perfectly.

Works great.

I use it to track usage/flow rates for my RO unit. . Connected to a ESP8266 & works fine with 3.3v supply .. simply connect it directly to a GPIO pin. Programmed the ESP8266 using ESPhome & use InfuxDB to store the data, Grafana to display. For example, to measure L/hr configure ESPhome as follows: - platform: pulse_counter pin: GPIO5 name: "Pulse Counter" update_interval: 60s filters: - lambda: return (x / 38.0) * 60.0; unit_of_measurement: "L/hr"

works well as a means of metering my custom cooling loop

With a little Teflon plumbers tape, this fits no problem with the standard G1/4 fittings used in most custom water cooling loops, and plugs right into a standard fan header to meter flow. A cheap and efficient means of ensuring that the water isn't obstructed in any way. For the record, water flow rate has negligible impact on overall cooling - just so long as there is flow. As such, I use this to set an alarm a,d shut down the computer - should the flow ever stop. cheap insurance.
