The FS1-6 paddle flow switch is designed to prove liquid flow in a wide variety of HVAC and industrial applications. The corrosion-resistant flow switch is mounted in a weather-resistant box for simple wiring connections. The polyphenylene sulfide plastic vane is field trimmable for 1" (2.54 cm) and larger pipes, and it is magnetically coupled to the SPDT switch to prevent liquid from entering the switch housing.

I've used this flow switch numerous times with flow rates of 3 gpm or greater. This switch did not perform well in a small diameter pipe with low flow (emergency eyewash station).
Pros: Good value
Cons: poor low flow response
Yes, I recommend this product.

Have used a few of these. unlike the brass switches, if something happens to the paddle it can't be replaced. Trimming the paddle is best done with a small saw. Once installed, they work great.
