This is not good product

Would Not Recommend

I been taking cold showers with a new hot water heater and that I changed my heating element and it still doesn’t work right now. So I need for someone to come in and fix this problem or order me a new one because it should not be broken with in three weeks of work time. Lowe’s you need to own up to this and everyone problems they have with this.

I picked this item up at your NE location. The most enjoyable part of this purchase was your employee (Henry) what a most pleasant, helpful and professional person. If all people had the attitude of this young man the world would be a much better place. Most Excellent experience!!!
