easy to install and light very happy so far, the water heater it lit up the very first time and it is still on. Had a bad experience before with a Rheem water heater before because after installing it, it would not light up and had to uninstall it and return to store and install another one. So this whirlpool lit up right away on first try. However, heater nipples not included and had to buy separately at store October 8, 2014

This product has great features I bought 2 of these water heaters very easy to install and easy to light. Keep our water plenty hot year round. Never had any problems with the 1st one. July 19, 2014
A quality product for the right price I did not have any issue while installing this product, and it has been 3 months and it is working fine June 22, 2014
Whirlpool Gas water heater Parts and tools needed for installation (printed on box) should include - (2) 4" nipples for the water supply to water heater connections. Without the nipples you can not install this water heater. Nipples connection installation should say - use teflon tape on connections. I first used pipe compound on both hot & cold nipples and they both leaked. I then re-installed with teflon tape and no leaks. June 10, 2014
Easy install. Very nicely thought out. Easily installed. Lowes has an excellent extended warranty service and a retired plumber actually helped me in making my decision that worked at Lowes. It took me a little over 2 hours from removing my old water heater to actually having hot water without any leaks. Good job!!!!! May 31, 2014
