 How to use at home (first week after surgery)? 
  
 
 Freeze 8–10 water bottles. Put them in the tank, add water, connect pad. Runs 14+ hours — no need to add ice all day. 
 
 
 
  
 Is it loud for chronic pain (like arthritis)? 
  
 
 No. Zip it closed — it’s quieter than a whisper. Set it to cycle (e.g., 15 min on / 45 min off) and run all night without noise. 
 
 
 
  
 How does “loop mode” work? 
  
 
 You set ON time and OFF time. Example: ON 20 min, OFF 40 min. It repeats until you turn it off. Great for overnight. 
 
 
 
  
 Will the connector leak? 
  
 
 No. Double seal and pressure-tested. Zip it closed — no wiggle. If it leaks, just push it back in until you hear a click. 
 
 
 
  
 Does fully closing the zipper pinch the water hose? 
  
 
 No. The hose connector is a rigid pass-through part. The zipper closes around it without crushing the hose. This design solves the “hose twisting / flow interruption” problem seen in competitors.
