Product review (5 stars): Great customer service from Z-Line!!!
I bought this unit 5 years ago, it has been working great, but recently it starts having on/off problem intermittently. After contacting the vendor's customer service, they sent me a control circuit board for me to replace, then everything is back to normal again. All I want to say is, they really care about their customer, and help to fix the problem. Even after 5 years, I still got a free replacement part from them. Thank you, Z-Line !!
