So far, a great pump for my cold plunge, MUCH better than what I got on Amazon. Seriously, don't waste your time there. Also, I had an issue with the setup: I emailed Joe, sent him some pictures per his request, and because he takes customer service so seriously, my cold plunge was correctly running with this new Danner pump within a few hours. I can't get that on Amazon. I'm a new fan of Joe's DIY Cold Plunge, and he's earned my future business.
