Hi,
It is a great spa for the price. While not being as full featured as the rest of the Watkins line, you can rest assured that it was manufactured properly! We have sold about 100 Sorrento's since they were launched and have had very few problems with them. As with all spas, I would recommend that you wet test the unit before buying to be sure it is right for you. Also, make sure you trust the dealer since they will be who you are dealing with for years to come. If both of them are OK, then I'd say go for it! Good luck!
