We purchased Dynasty spa (Club 8L) from World of Spas almost 4 years ago and wanted to share that it is working as great as the day we received it. Customer support for chemicals and questions has been wonderful. The design of the spa that prevents mice from getting inside the tub has worked as advertised. Not a sign of any critters. We had to get rid of our Polar Spa due to infestation of mice. If you are looking for a high quality tub World of Spas is worth a look
