This hot tub is great for the price, jets are strong enough and it’s very comfortable. My only issues are the heater.....it loses heat very fast...about a degree every 15 min or 
so.  Also...this is pretty small for a 4-5 
person.  I think 3 fit well, more than that would be a little too close. We are happy with it though...we keep it at 104, and it stands up to a good hour of use before it 
cools too much.
