Compact and simple for home use

Works well for home use. The setpoint runs about 5 degrees higher before cooling back down, likely to reduce cycling and extend compressor life. The water pump does not shut off with the digital buttons, so the power toggle must be switched off when the cooling wand is out of the water to avoid burning out the pump. Cooling takes time, but the bathroom outlet and circuit breaker have never tripped. The app was not tried. Suggested additions include a digital pump switch and indicator, plus wheels and a handle for portability.

Pros
  • + compact and simple
  • + never tripped the bathroom outlet or circuit breaker
Cons
  • − setpoint has a 5 degree difference
  • − water pump does not turn off with digital buttons
  • − cooling takes time

Works well outdoors with no setup needed

This chiller requires no setup: it can be taken out of the box and plugged in. After several months of use, it has worked without issues. Unlike most other chillers, it is designed to work outdoors. A pool skimmer for the tub and a waterproof cover for an outdoor ottoman were purchased separately to protect the chiller during heavy rain.

Pros
  • + No setup required
  • + Works reliably over several months
  • + Suitable for outdoor use

Effective chiller with strong support and easy setup

This chiller works well and is easy to use, with a single hose and pump that sits in the water to exchange tub water. It runs continuously and maintains the set temperature within 5 degrees. The WiFi performs well, though the app lacks a recurring on/off schedule because the unit is designed to run continuously. More app features would be welcome. The first unit failed to hold temperature, but customer service responded quickly, troubleshooting via text and video call, and sent a replacement with expedited shipping. Pairs well with a sauna.

Pros
  • + easy to use
  • + maintains temperature within 5 degrees
  • + WiFi works well
  • + responsive customer service
  • + replacement sent with expedited shipping
Cons
  • − first unit was defective
  • − no recurring schedule in app
  • − app could use more features

Works great in any tub

This chiller works well and fits any tub. Cooling a tub takes a while, which is likely typical for this type of unit. Using a filter that circulates the water is recommended to keep it clean and help cooling by mixing the temperature. The filter does not need to run constantly, but it helps during initial cooling and enough afterward to maintain clean water. With an insulated tub and cover, the water stays at the desired temperature without using much electricity and with little hassle.

Pros
  • + fits any tub
  • + keeps water at desired temperature
  • + low electricity use
  • + hassle-free
Cons
  • − takes a while to cool a tub
