Very helpful customer service

I knew basically what I required but didn’t know all the options, so I called and got excellent customer service. They showed me where on the website the items were that would fit my application, and the items came within 3 days of ordering. I would definitely order from them again.

I have not yet had the time to put everything together, but will rate the sensor and pump once I do.

good service.

"Easy to install, easy to set up, and easy calibration - just what I was looking for."
