I own a Fouwinds spa, model Key Largo for one year now. They are build in Smyrna-tennessee. The pumps (2 aqualflow 2xpe) are rather loud. They are directly mounted on the wooden cabinet and not on Rubber "pads". It´s funny tough that on their website they say they do.
I had some trouble with this spa:
-One corner of the wooden cabinet doesn´t fit right.
-The subwoofer of the stereo system was broken from day 1.(replaced)
-The low flow function of the pump didin´t work.(wrong "elko" from the Aquaflow company, doesn´t work right on the 50hz european power).(repaired)
-The display of the JBL radio didin´t work.(replaced)
-There were scratches in the schell.
-The ozonator was inop after 2 months(they installed a new one).the new one is inop again.
-Last week i discovered a leak at the valve to adjust the waterfall. Water is now dropping on top of the pump.(the service company will come to repair this).
The insulation of the cabinet could be better, it allowes much draft inside of the cabinet. My electrical costs are (16,53 euro ct per kWh) 80 Euros=104 Dollar per month. Our winter (Germany) was very mild min. 0 degrees centigrade, most of the time it was 4-7 degrees.
the good thing is, it has alot of options like a stereo , led light and steel jets.
