My water heater failed o light up and produce hot water. My decision to replace it via a large box store was thwarted by "bait and switch' tactics. So, as the heater was not leaking, a common cause for replacement, it must be the controls. I found almost the exact replacement. it was promptly shipped. In the original box. and in new condition with all documents. After a bit of travails, I got it installed and working perfectly. No water or gas leaks. Perfect solution at a fraction of the cost, less than 10%. As good as it gets.Vendor, product, Amazon and UPS performed perfectly.
