It is a good spa, especially for the price. It definitely has room for up to four FIT adults. I do, however, have one concern. The mold they use to create the spa leaves it with tiny plastic pills that you can feel. I do not know if there is a way to slice/cut/burn these off, but beware of them making runs or tears in your swimsuit.  

Living in a cooler environment, I also wish it came pre-winterized.

Pros: Great value, easy setup, pleasing design
Cons: Plastic pills in the mold
