This is a great spa especially for the money!  Get the ozonator because that reduces any chemicals you will need without one.  It's about $200 more but saves you a lot of money in the long run, especially your health.  The ozonator actually sterilizes the spa.  The spa is considered a 3-4 person spa.  Yes, 4 people can have the most absolute fun!  If you like to lay out in it, 2 people max.  The jets can be more powerful but they are enough for me...and I like very hard pulses.  The look of the spa sold me- I love it Grecian and that's the way it is...not the old fashioned wood look!  I highly recommend it!
