### 1/5 — Does not pair w cold plunge

*2026-08-19, version 4.7*

Persistent problems pairing and will not hold temp
Hard to navigate to repair dysfunctional plunge

### 1/5 — Eco mode

*2026-08-18, version 4.7*

Does not function 
Software is not working properly

### 1/5 — Cold plunge

*2026-08-14, version 4.7*

This cold plunge sucks!!! Don’t get!!! Buy from someone else!!! The people here so don’t care

### 5/5 — Cool! Literally!

*2026-08-11, version 4.7*

This Plunge is a life changer! So easy to use! I love the app! So cool, literally!

### 1/5 — Cold plunge

*2026-08-10, version 4.7*

This cold plunge sucks!!! Don’t get!!! Buy from someone else!!!

### 1/5 — No customer service

*2026-07-22, version 4.7*

Honestly you spend thousands of dollars on a product and there is hardly any customer service other than texting!? System keeps dropping out on the WiFi (not the WiFi’s fault, running consistently at 350mpbs). When you get the bath installed you cannot upgrade the firmware. You can’t control it from the app because it drops out every few minutes. Complete waste of money

### 5/5 — Flawless

*2026-07-11, version 4.6*

Insanely efficient and easy to manage. The best reset for a good or a bad day. Powerful and responsive. The app connects us to our reset.

### 4/5 — Solid app

*2026-07-06, version 4.6*

Solid experience and glad they have the app. But need to add ability to see temp in Celsius and bring back Apple Watch support or whoop and integrate heart rate data in each session

### 1/5 — Very Delayed Support

*2026-06-26, version 4.6*

After investing over $10,000 into this bathtub, we are still waiting for PLUNGE Support to email us back why our PLUNGE cannot seem to stay on. We have an email that is asking for metrics which we don’t have access to because the electrical system for the PLUNGE is down. Very disappointing. PLUNGE support emails are not monitored with any frequency apparently. If we had known better, we should have returned this unit within 30 days. Now we are stuck with this horrible investment and we are at the mercy of PLUNGE Support. If we do not have the unit fixed using the warranty system, then no future damage will be covered under warranty. We are being held hostage. Caveat Emptor

### 1/5 — No Centigrade option?

*2026-06-21, version 4.6*

Bit of an oversight?
