BUY IT!
It arrived a couple of days early and was well-wrapped. 
It is light enough to move easily before it has water in it.
We used two garden hoses to fill it (thinking it would take a long time if we only used one). It was full in 20 minutes!
Plugged in and waited a couple of minutes, and the jets came on as expected. 
The only downside for me is that I have no experience in spa chemical usage. The manual isnt explicit enough, for me. I went by the instructions on the chemical bottles and Google. 
I would buy it again, with no hesitation!
