## What reviewers say

**Cold Stoic 2.0** — One whitelisted hands-on tester body verified: BarBend, which tested the Renu Cold Stoic 2.0 in its own facility. Verdict: a beautifully built, exceptionally clean, well-insulated luxury tub whose integrated chiller cools painfully slowly and whose near-$10,000 starting price is hard to justify (2.5/5 for value, 1/5 for portability).
