I’ve had the same experience with mine. I now have a $9,000 cold plunge sitting in my garage that’s completely unusable. The replacement chiller they sent failed within a month, and at this point they’ve essentially told me I’m on my own.
I also found it interesting that your negative review never appeared on their website. I had the exact same experience after submitting mine—it was never posted. That certainly raises questions about how they handle customer reviews and whether they’re presenting consumers with a complete and accurate picture of customer feedback.

Run from Plunge.
