Happy with product, not happy with the way the warranty needs to be processed, frustrating to the point of just paying for a new unit, transferred to multiple departments, spoke to multiple people, emailed a number of pictures, requested to speak to supervisors, and was told the supervisor is not available, seemed extremely ridiculous, again horrible warranty experience, fortunate the unit itself is a great price point and ended just buying another unit Richard was very helpful and attentive assisting with the purchase of the new Tankless heater, he gets a very good review! Again seems like a good product just terrible warranty department
