Similar to other customers, I bought a chlorinator cell that never worked to replace a Jandy unit. I wrote to them several times and when they did respond they blamed it on the control unit ( which is new) and saying I needed to spike the chlorine. Of course chlorine production is the job of the Chlorinator in the first place. I filled out their warranty form and after several follow ups including documentation of pool tests, they are not responding. Do not be fooled by the 5 year warranty or low prices, their whole business model is based on deceiving customers with defective products. A class action law suit should be filed against this unethical company, stay clear of this company.
