It gets 4* B/C of Pool & Hot Tub Depot's GREAT service
The heater coil on the original blew out & melted the top connection box in a week. That just tells me shoddy manufacturing on this element tube. Funny, but in our modern era that was the 3rd time this year that a product out of the box failed. Which says more about the state of manufacturing than anything else. BUT Pool & HT Depot stood behind it like champs, shipping me a replacement in 2 days. The replacement's been in service now for 2 weeks and all is well. I'd give the heater 2 stars for the quality (get a better one if it's available) but Pool and Hot Tub Depot are one of the BEST companies online to deal with.
