This product has easy features to control the temperature and I like that it can be set for vacation mode and an energy efficient setting. This product was easy to use and I like that it has an energy efficient setting plus a vacation setting and easy to use for setting the temperature. Just installed but being that it is a Whirlpool brand and made in the USA I believe it will be very reliable. My kitchen appliances are all Whirlpool as well as my washer and dryer. I've always had good experiences with Whirlpool brands. September 2, 2014

Great features for the price! Super easy to install. Up and running very fast. Had hot water within an hour and a half of filling the tank up. Would highly recommend for anyone looking to upgrade or replace. Being able to adjust temp without removing top panel is awesome. August 26, 2014
This unit has great appearan and ease of operation After reading many reviews I liked the idea of the energy smart feature that remembers usage. The contractor that installed found it very easy and also liked the features. I am hoping for some savings on energy bills but will have to see after a couple of months. Reviews indicated that some people had issues with flow restrictions but I have experienced no problems. August 20, 2014
great features The water heater was very ease to install. The contractor had it installed and operating in less than an hour. August 20, 2014
This product was easy to install and works great I found this product to be very easy to install. I didn't run into any difficulty and the instructions provided were very clear. There were also diagrams on how to properly wire the product. Also the instructions were very helpful with the operation of this heater. This particular model has a digital display with options to allow for energy saving opportunities. This is especially useful for vacations. This model will likely pay for itself just based on efficiency. I have always enjoyed Whirlpool products and this water heater is no exception. Thanks to the research and development team and all who helped to make a fine product. August 13, 2014
