I've had this spa for a whole week now. I like the lounger, it is just about the right size for me (5'7"). I tend to think the back is a little too upright for my taste, but not uncomfortable. Other than the ones on the filter housing cover, the drink holders are basically useless, as they slant too much and I fear any drink set in them will fall over. The filter housing cover has four beer can size and one large holder. It is relatively quite, even with the jets on high, and the air valve fully open.
One other design flaw in my opinion - The pump drain is at the 9'oclock postion instead of the 6 o'clock position, meaning you can't drain all the water out of the pump.
I did not get the radio option (I have a boom box on the deck), the LEDs (I like the dark, and watching the stars - no unnecessary light allowed at night). It does come with the waterfall standard now, but after a few days, I turned if off. I'm sure it will alternate - on some days/off others.
The one thing I did not get that I may want is a cover lift, but that would necessitate moving the tub ~10" away from the raised deck it sits next to.. I am toying with building a slanting slide off the side (Not enough room for a shelf). If my idea works, won't need the lift.
