Easy to use, just read all the instructions. Confirm your water temperature is 75 degrees Fahrenheit. When it's warmer, like mine is 79 degrees Fahrenheit, I've had to set the dive time to 18 seconds. I used them to set up a Pelican Water WF6 whole house water purification system. These are the same ones they provide with the original purchase.
