well after very careful considerationwe decided on th heet. boy are we sorry we bought such a lemon in the first yesr we had to have the main control panelreplacec 3 times. in year 2 we had to get a new 2 speed pump because ours went out. year 3 we needed to replace the ozonztor. and shortly after the warenty was up we developed a leek. to fix that problem we just turned the seat off and wala, no more leek. now we found a second leek and the tub wont even power up. it's been nothing but a hunk of junk.don't buy. la spas does nothing after the warrenty period.
