Super customer service. Especially after the sale. Two or three times they came out after the sale. They worked with the manufacturer and replaced the control at no charge

I have been using them for years for various jobs. Both pool and hot tub. They can do it all

We use them regularly for closing our inground pool in the fall, we open ourselves in spring. We take a sample in and get water tested to see what dosage of chemicals it needs after winter cover comes
