Size and ease of installation

Would Recommend

The size of the hot water heater is very convenient and easy to install Instructions need a little work, though. My clarification of some sort but other than that that if you know what you're doing Or have common senseyou should have no problem installing

Fit the bill......

Old water heater rusted out at the bottom so needed a replacement. This model ws priced reasonably, had the capacity, met the height needed, plus provided the 6-year warranty. Time will tell but expecting the best!

Tank itself is fine, their incompetent delivery..

Would Not Recommend

Tank itself is good I'm sure, but my wife watched the guy literally drop it outta the back of his ford escape n theirs a huge dent in the bottom 😡 they need to actually have their own delivery service n not just hire incompetent dudes w a suv to deliver stuff... I paid almost 700$ n got a damaged product..
