Good service but part quality is poor
The first one I bought from you only lasted a year that's why I had to buy another one

I needed this part, y'all had it in stock.
Special ignition cable for a Polaris water heater. One supplier in my area, hard to deal with.
Supplyhouse had it, good price, got it right away to replace my Frankenstein temp repair. Thank you for being there. Used you times before, always great to deal with!

The product to worked great
Having said that the product worked great I'll follow up with the big butt. But I asked them to throw in a magnetic business card I could put on the partition between the front of my van and the back so I could remember where I bought it. They didn't. I'll probably never remember who I bought this from ever again.
